[PATCH v4 0/8] iio: adc: dfsdm: add scaling support
by Olivier Moysan 08 Jul '24

08 Jul '24

The aim of this serie is to add scaling support to STM32 DFSDM peripheral in the analog context. The DFSDM currently operates as a consumer of IIO channels provided by a generic SD modulator. As previously discussed in RFC [1], this topology is not suitable for implementing scaling. This series brings the integration of the DFSDM driver with the new IIO backend framework [2], enabling the DFSDM IIO device to offer scaling feature based on reference voltage data obtained from the IIO SD modulator backend. This generic SD modulator backend takes the place of the former SD modulator, used with legacy implementation. The DFSDM driver has been updated to adopt the generic ADC channel binding [3]. The reasons for this include: - Reducing the use of proprietary properties - Simplifying the coexistence of legacy and new backend bindings - Prepare the support of the MDF peripheral on STM32MP25 SoC Backward compatibility is maintained through legacy support. This series extends the backend framework with the following APIs: - iio_backend_read_raw: This API is intented to retrieve channel attributes from the backend. It is based on IIO framework read_raw API. - iio_backend_read_scale / iio_backend_read_offset Dedicated APIs to read scale and offset channel values. - iio_backend_disable / iio_backend_enable: backend enable/disable to be used for PM management - devm_iio_backend_fwnode_get Intended for parsing DT subnodes to allow generic channel binding support, as generic channel DT nodes are not populated as devices.

[PATCH v6 5/7] ASoC: dt-bindings: update fsl-asoc-card bindings after imx-spdif merge
by Elinor Montmasson 08 Jul '24

08 Jul '24

The S/PDIF audio card support with compatible "fsl,imx-audio-spdif" was merged from imx-spdif into the fsl-asoc-card driver. It makes possible to use an S/PDIF with an ASRC. This merge introduces new DT bindings to use with compatible "fsl,imx-audio-spdif" to follow the way fsl-asoc-card works: * the "spdif-controller" property from imx-spdif is named "audio-cpu" in fsl-asoc-card. * fsl-asoc-card uses codecs explicitly declared in DT with "audio-codec". With an SPDIF, codec drivers spdif_transmitter and spdif_receiver should be used. Driver imx-spdif used instead the dummy codec and a pair of boolean properties, "spdif-in" and "spdif-out". In an upcoming commit, in-tree DTs will be modified to follow these new properties: * Property "spdif-controller" will be renamed "audio-cpu". * spdif_transmitter and spdif_receiver nodes will be declared and linked to the fsl-asoc-card node with the property "audio-codec". To keep backward compatibility with other DTs, support for "spdif-controller", "spdif-in" and "spdif-out" properties is kept. However, it is recommended to use the new properties if possible. It is better to declare transmitter and/or receiver in DT than using the dummy codec. DTs using compatible "fsl,imx-audio-spdif" are still supported, and fsl-asoc-card will behave the same as imx-spdif for these DTs.

by Shenghao Ding 08 Jul '24

08 Jul '24

Use get_unaligned_be16 instead of be16_to_cpup and get_unaligned_be32 instead of be32_to_cpup for potentially broken alignment.

Fix labeling of BOSS Katana ports
by GitHub pull_request - opened 06 Jul '24

06 Jul '24

alsa-project/alsa-ucm-conf pull request #430 was opened from aledomu: I'd like to rename the MIDI ports as well but I don't know how. If you can point me where I can learn about it, I'll be glad to do so and mark this PR as finished. I guess this fix works the same for all Katana models from all generations, but I don't have the PID available to enable it, nor the devices for testing.

[PATCH alsa-utils 1/5] aplaymidi2: Add initial version
by Takashi Iwai 06 Jul '24

06 Jul '24

aplaymidi2 is a program similar like aplaymidi, but intended for playing back a MIDI Clip file that was introduced for handling UMP. MIDI Clip file contains UMP packets, and its structure is much simpler than SMF. The options are mostly same as aplaymidi, but I omitted -l option for simplifying the code.

[PATCH alsa-lib] seq: Add API functions to set different tempo base values
by Takashi Iwai 06 Jul '24

06 Jul '24

MIDI2 Set Tempo message uses 10ns-based values, and we need to update the API to change the base time unit. This patch adds a few new API functions: - snd_seq_has_queue_tempo_base() returns 1 if the client supports a new tempo-base value; if 0, it's an old system and application has to use the tempo in the fixed 1us unit - the tempo base can be changed with snd_seq_queue_tempo_set_tempo_base(), provided in nsec unit; the value has to be either 10 or 1000 (or 0 as default, equivalent with 1000) The protocol version is checked and fallback to the fixed 1us base for the old clients.

Add support for a new DAC
by Pino Abete 05 Jul '24

05 Jul '24

Hi, I'm not an expert and I'm sorry if this is the wrong place for thsi kind of requests. I'm trying to add native DSD support for this integrated DAC/amplifier: https://www.mission.co.uk/778x/ Unfortunately, vendor is not collaborative. It should support up to 384kHz (PCM) and DSD256 and have a XMOS USB chip and a ESS Sabre32 ES9018K2M DAC chip. I tried simply to add: case USB_ID(0x2622, 0x0011): /* Mission 778X */ in the "switch" section under /* XMOS based USB DACs */ and it works with the DSD_U32_BE format (tried using MPD - Music Player Demo). Is it possible to officially add this to source or do you need a request from OEM? Thanks --

[PATCH] ASoC: SOF: Intel: hda: fix null deref on system suspend entry
by Pierre-Louis Bossart 04 Jul '24

04 Jul '24

From: Kai Vehmanen <kai.vehmanen(a)linux.intel.com> When system enters suspend with an active stream, SOF core calls hw_params_upon_resume(). On Intel platforms with HDA DMA used to manage the link DMA, this leads to call chain of hda_dsp_set_hw_params_upon_resume() -> hda_dsp_dais_suspend() -> hda_dai_suspend() -> hda_ipc4_post_trigger() A bug is hit in hda_dai_suspend() as hda_link_dma_cleanup() is run first, which clears hext_stream->link_substream, and then hda_ipc4_post_trigger() is called with a NULL snd_pcm_substream pointer.

[PATCH] ASoC: SOF: ipc4-topology: Use single token list for the copiers
by Pierre-Louis Bossart 04 Jul '24

04 Jul '24

From: Peter Ujfalusi <peter.ujfalusi(a)linux.intel.com> There is no need to keep separate token list for dai and 'common' copier token list when the 'common' list is actually the aif list, the SOF_COPIER_DEEP_BUFFER_TOKENS are not applicable for buffers. We could have separate lists for all types but it is probably simpler to just use a single list for all types of copiers.

[alsa-devel] unsupported variant of snd_hda_intel

Hello, I have an Acer Aspire 4736G laptop. The soundcard that is shipped in this laptop is intel-hda based as shown (actually it's a realtek): cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0x9b300000 irq 46 Basic sound output is correct but few feature are missing: - internal mic seems to be found but do not works. - sound output stop working when trying to send it using HDMI output - heads do not work when plugged neither when forcing pulseaudio to use it. I have an ubuntu 10.10 which is shipped with alsa 1.0.23. I have googled around and tried loading the snd-hda-intel with several parameters () as found in HD-Audio-Models.txt to no avail. cat /proc/asound/pcm 00-00: ALC888 Analog : ALC888 Analog : playback 1 : capture 1 00-01: ALC888 Digital : ALC888 Digital : playback 1 00-03: NVIDIA HDMI : NVIDIA HDMI : playback 1 Where can I begin to help implement the support for this sound card? I have very skills in developement in general but am ready to try if it is not to hard (I supose I can use previous code for similar models).. I just need a shepherd. Thanks

[PATCH 0/4] ASoC: tas*: Fix up GPIO usage
by Linus Walleij 04 Jul '24

04 Jul '24

The TI TAS drivers use some legacy GPIO code and headers, this series fixes it up. The TAS2781 is a special case since it adds a handful of lines of deviating code to reconfigure a GPIO line for IRQ mode and then never actually use the IRQ obtained in the code. Is the line used by autonomous hardware? I'm puzzled by this. Anyways the patch suggest how to solve this properly by fixing the parent irqchip and I'm happy to help.

[PATCH v2] slimbus: Fix struct and documentation alignment in stream.c
by Amit Vadhavana 03 Jul '24

03 Jul '24

The placement of the `segdist_codes` array documentation was corrected to conform with kernel documentation guidelines. The `@segdist_codes` was placed incorrectly within the struct `segdist_code` documentation block, which led to a potential misinterpretation of the code structure. The `segdist_codes` array documentation was moved outside the struct block, and a separate comment block was provided for it. This change ensures that clarity and proper alignment with kernel documentation standards are maintained. A kernel-doc warning was addressed: ./drivers/slimbus/stream.c:49: warning: Excess struct member 'segdist_codes' description in 'segdist_code' Signed-off-by: Amit Vadhavana <av2082000(a)gmail.com> --- Changes in v2: - Removed `static const` keyword from `segdist_code` structure declaration. drivers/slimbus/stream.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/drivers/slimbus/stream.c b/drivers/slimbus/stream.c index 1d6b38657917..863ab3075d7e 100644 --- a/drivers/slimbus/stream.c +++ b/drivers/slimbus/stream.c @@ -18,15 +18,17 @@ * and the first slot of the next consecutive Segment. * @segdist_code: Segment Distribution Code SD[11:0] * @seg_offset_mask: Segment offset mask in SD[11:0] - * @segdist_codes: List of all possible Segmet Distribution codes. */ -static const struct segdist_code { +struct segdist_code { int ratem; int seg_interval; int segdist_code; u32 seg_offset_mask; -} segdist_codes[] = { +}; + +/* segdist_codes - List of all possible Segment Distribution codes. */ +static const struct segdist_code segdist_codes[] = { {1, 1536, 0x200, 0xdff}, {2, 768, 0x100, 0xcff}, {4, 384, 0x080, 0xc7f}, -- 2.25.1

[PATCH 0/2] ASoC: cs35l56: Set correct upper volume limit
by Richard Fitzgerald 03 Jul '24

03 Jul '24

These two commits set the upper limit of the Speaker Volume control to +12dB instead of +100dB. This should have been a simple 1-line change to the #define in the header file, but only the HDA cs35l56 driver is using this define. The ASoC cs35l56 driver was using hardcoded numbers instead of the header defines. So the first commit changes the ASoC driver to use the #defined constants.

[PATCH] ASoC: fsl_xcvr: Improve suspend/resume flow in fsl_xcvr_trigger()
by Chancel Liu 03 Jul '24

03 Jul '24

In the current flow all interrupts are disabled in runtime suspend phase. However interrupts enablement only exists in fsl_xcvr_prepare(). After resume fsl_xcvr_prepare() may not be called so it will cause all interrupts still disabled even if resume from suspend. Interrupts should be explictily enabled after resume. Also, DPATH reset setting only exists in fsl_xcvr_prepare(). After resume from suspend DPATH should be reset otherwise there'll be channel swap issue.

[PATCH v3 0/8] iio: adc: dfsdm: add scaling support
by Olivier Moysan 03 Jul '24

03 Jul '24

The aim of this serie is to add scaling support to STM32 DFSDM peripheral in the analog context. The DFSDM currently operates as a consumer of IIO channels provided by a generic SD modulator. As previously discussed in RFC [1], this topology is not suitable for implementing scaling. This series brings the integration of the DFSDM driver with the new IIO backend framework [2], enabling the DFSDM IIO device to offer scaling feature based on reference voltage data obtained from the IIO SD modulator backend. This generic SD modulator backend takes the place of the former SD modulator, used with legacy implementation. The DFSDM driver has been updated to adopt the generic ADC channel binding [3]. The reasons for this include: - Reducing the use of proprietary properties - Simplifying the coexistence of legacy and new backend bindings - Prepare the support of the MDF peripheral on STM32MP25 SoC Backward compatibility is maintained through legacy support. This series extends the backend framework with the following APIs: - iio_backend_read_raw: This API is intented to retrieve channel attributes from the backend. It is based on IIO framework read_raw API. - iio_backend_read_scale / iio_backend_read_offset Dedicated APIs to read scale and offset channel values. - iio_backend_disable / iio_backend_enable: backend enable/disable to be used for PM management - devm_iio_backend_fwnode_get Intended for parsing DT subnodes to allow generic channel binding support, as generic channel DT nodes are not populated as devices.

[PATCH] firmware: cs_dsp: Don't allow writes to read-only controls
by Richard Fitzgerald 02 Jul '24

02 Jul '24

Add a check to cs_dsp_coeff_write_ctrl() to abort if the control is not writeable. The cs_dsp code originated as an ASoC driver (wm_adsp) where all controls were exported as ALSA controls. It relied on ALSA to enforce the read-only permission. Now that the code has been separated from ALSA/ASoC it must perform its own permission check. This isn't currently causing any problems so there shouldn't be any need to backport this. If the client of cs_dsp exposes the control as an ALSA control, it should set permissions on that ALSA control to protect it. The few uses of cs_dsp_coeff_write_ctrl() inside drivers are for writable controls.

[PATCH] drivers:soundwire: qcom: cleanup port maask calculations
by Srinivas Kandagatla 02 Jul '24

02 Jul '24

Cleanup the port map calculations, existing masks of having separate masks for in and out ports is not really required. Having a single mask for all the ports in the controller is simple and cuts of some unnecessary code.

[PATCH] ASoC: tas5805m: demystify DSP volume control coefficients
by Felix Kaechele 02 Jul '24

02 Jul '24

The original manufacturer sample driver code uses direct DSP register writes to control digital volume on this amplifier without further context as to why it's not using the documented DIG_VOL_CTRL register. A thread in the manufacturer's forums [1] suggests this might have been done to work around volume ramping being used when controlling the volume through the DIG_VOL_CTRL register. When volume is controlled through this register, reading and/or writing any register is blocked until the volume ramping has concluded and the setpoint is reached. Additionally, the sample code uses a lookup table to map decibel values to 9.23 formatted coefficients. For posterity, add references to where this is documented and why a lookup table may be used.

[PATCH] ASoC: fsl: lpc3xxx-i2s: Avoid using ret uninitialized in lpc32xx_i2s_probe()
by Nathan Chancellor 01 Jul '24

01 Jul '24

clang points out that ret may be used uninitialized in lpc32xx_i2s_probe() in an error pointer path (which becomes fatal with CONFIG_WERROR): sound/soc/fsl/lpc3xxx-i2s.c:326:47: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized] 326 | "failed to init register map: %d\n", ret); | ^~~ sound/soc/fsl/lpc3xxx-i2s.c:310:9: note: initialize the variable 'ret' to silence this warning 310 | int ret; | ^ | = 0 1 error generated. One solution would be a small refactoring of the second parameter in dev_err_probe(), PTR_ERR(i2s_info_p->regs), to be the value of ret in the if statement. However, a nicer solution for debugging purposes, which is the point of this statement, would be to use the '%pe' specifier to symbolically print the error pointer value. Do so, which eliminates the uninitialized use of ret, clearing up the warning.

[PATCH] driver core: have match() callback in struct bus_type take a const *
by Greg Kroah-Hartman 01 Jul '24

01 Jul '24

In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: "Rafael J. Wysocki" <rafael(a)kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- - cc: list suppressed as it just touches too many different subsystems at once, sorry.

[PATCH 00/10] Add support for non-interleaved mode in qmc_audio
by Herve Codina 01 Jul '24

01 Jul '24

The qmc_audio driver supports only audio in interleaved mode. Non-interleaved mode can be easily supported using several QMC channel per DAI. In that case, data related to ch0 are sent to (received from) the first QMC channel, data related to ch1 use the next QMC channel and so on up to the last channel. In terms of constraints and settings, the interleaved and non-interleaved modes are slightly different. In interleaved mode: - The sample size should fit in the number of time-slots available for the QMC channel. - The number of audio channels should fit in the number of time-slots (taking into account the sample size) available for the QMC channel. In non-interleaved mode: - The number of audio channels is the number of available QMC channels. - Each QMC channel should have the same number of time-slots. - The sample size equals the number of time-slots of one QMC channel. This series add support for the non-interleaved mode in the qmc_audio driver and is composed of the following parts: - Patches 1 and 2: Fix some issues in the qmc_audio - Patches 3 to 6: Prepare qmc_audio for the non-interleaved mode - Patches 7 and 8: Extend the QMC driver API - Patches 9 and 10: The support for non-interleaved mode itself Best regards, Hervé Herve Codina (10): ASoC: fsl: fsl_qmc_audio: Check devm_kasprintf() returned value ASoC: fsl: fsl_qmc_audio: Fix issues detected by checkpatch ASoC: fsl: fsl_qmc_audio: Split channel buffer and PCM pointer handling ASoC: fsl: fsl_qmc_audio: Identify the QMC channel involved in completion routines ASoC: fsl: fsl_qmc_audio: Introduce qmc_audio_pcm_{read,write}_submit() ASoC: fsl: fsl_qmc_audio: Introduce qmc_dai_constraints_interleaved() soc: fsl: cpm1: qmc: Introduce functions to get a channel from a phandle list soc: fsl: cpm1: qmc: Introduce qmc_chan_count_phandles() dt-bindings: sound: fsl,qmc-audio: Add support for multiple QMC channels per DAI ASoC: fsl: fsl_qmc_audio: Add support for non-interleaved mode. .../bindings/sound/fsl,qmc-audio.yaml | 41 +- drivers/soc/fsl/qe/qmc.c | 32 +- include/soc/fsl/qe/qmc.h | 27 +- sound/soc/fsl/fsl_qmc_audio.c | 590 +++++++++++++----- 4 files changed, 505 insertions(+), 185 deletions(-) -- 2.45.0

[PATCH 0/6] ASoC: codecs: wsa88xx: add support for static port mapping.
by srinivas.kandagatla＠linaro.org 27 Jun '24

27 Jun '24

Existing way of allocating soundwire master ports on Qualcommm platforms is dynamic, and in linear order starting from 1 to MAX_PORTS. This will work as long as soundwire device ports are 1:1 mapped linearly. However on most Qcom SoCs like SM8550, SM8650, x1e80100, these are NOT mapped in that order. The result of this is that only one speaker among the pair of speakers is always silent, With recent changes for WSA codec to support codec versions and along with these patches we are able to get all speakers working on these SoCs.

[PATCH 0/3] ASoC: imx-audmix: Split capture device to be a new device
by Shengjiu Wang 27 Jun '24

27 Jun '24

The transmitter and receiver part of the SAI interface need to be configured with different master/slave mode, especially to work with the audiomix module. The SAI1 TX is in master mode, but SAI1 RX is in slave mode. So add another two DAIs for TX and RX separately in fsl_sai driver. There will be three devices for audiomix sound card, hw:x,0 is the playback device for one SAI, hw:x,1 is the playback device for another SAI, hw:x,2 is the capture device for audmix output.

[PATCH v6 7/7] ARM: dts: imx6: update spdif sound card node properties
by Elinor Montmasson 27 Jun '24

27 Jun '24

The merge of imx-spdif driver into fsl-asoc-card brought new DT properties that can be used with the "fsl,imx-audio-spdif" compatible: * The "spdif-controller" property from imx-spdif is named "audio-cpu" in fsl-asoc-card. * fsl-asoc-card uses codecs explicitly declared in DT with "audio-codec". With an S/PDIF, codec drivers spdif_transmitter and spdif_receiver should be used. Driver imx-spdif used instead the dummy codec and a pair of boolean properties, "spdif-in" and "spdif-out". While backward compatibility is kept to support properties "spdif-controller", "spdif-in" and "spdif-out", using new properties has several benefits: * "audio-cpu" and "audio-codec" are more generic names reflecting that the fsl-asoc-card driver supports multiple hardware. They are properties already used by devices using the fsl-asoc-card driver. They are also similar to properties of simple-card: "cpu" and "codec". * "spdif-in" and "spdif-out" imply the use of the dummy codec in the driver. However, there are already two codec drivers for the S/PDIF, spdif_transmitter and spdif_receiver. It is better to declare S/PDIF Tx and Rx devices in a DT, and then reference them with "audio-codec" than using the dummy codec. For those reasons, this commit updates in-tree DTs to use the new properties: * Rename "spdif-controller" property to "audio-cpu". * Declare S/PDIF transmitter and/or receiver devices, and use them with the "audio-codec" property instead of "spdif-out" and/or "spdif-in". These modifications were tested only on an imx8mn-evk board. Note that out-of-tree and old DTs are still supported.

[PATCH v6 4/7] ASoC: fsl-asoc-card: merge spdif support from imx-spdif.c
by Elinor Montmasson 27 Jun '24

27 Jun '24

The imx-spdif machine driver creates audio card to directly use an S/PDIF device. However, it doesn't support interacting with an ASRC. fsl-asoc-card already has the support to create audio card which can use the ASRC. Merge the S/PDIF support from imx-spdif into driver fsl-asoc-card to extend the support of S/PDIF audio card with the use of ASRC devices. fsl-asoc-card uses slightly different DT properties than imx-spdif: * the "spdif-controller" property from imx-spdif is named "audio-cpu" in fsl-asoc-card. * fsl-asoc-card uses codecs explicitly declared in DT with "audio-codec". With an SPDIF, codec drivers spdif_transmitter and spdif_receiver should be used. Driver imx-spdif used instead the dummy codec and a pair of boolean properties, "spdif-in" and "spdif-out". To keep backward compatibility, support for "spdif-controller", "spdif-in" and "spdif-out" is also added to fsl-asoc-card. However, it is recommended to use the new properties if possible. It is better to declare transmitter and/or receiver in DT than using the dummy codec. DTs using compatible "fsl,imx-audio-spdif" are still compatible, and fsl-asoc-card will behave the same as imx-spdif for these DTs.

[PATCH v6 3/7] ASoC: fsl-asoc-card: add compatibility to use 2 codecs in dai-links
by Elinor Montmasson 27 Jun '24

27 Jun '24

Adapt the driver to work with configurations using two codecs or more. Modify fsl_asoc_card_probe() to handle use cases where 2 codecs are given in the device tree. This will be needed to add support for the SPDIF. Use cases using one codec will ignore any given codecs other than the first.

[PATCH v6 2/7] ASoC: fsl-asoc-card: add second dai link component for codecs
by Elinor Montmasson 27 Jun '24

27 Jun '24

Add a second dai link component for codecs that will be used for use cases with 2 codecs. It is needed for future integration of the SPDIF support, which will use spdif_receiver and spdif_transmitter drivers. To prevent deferring in use cases using only one codec, also set by default the number of codecs to 1 for the relevant dai links.

0db0:543d Micro Star International USB Audio
by GitHub issues - opened 27 Jun '24

27 Jun '24

alsa-project/alsa-ucm-conf issue #427 was opened from vividnightmare: I have MSI TRX40 Pro 10G on Arch Linux. alsa-ucm-conf 1.2.12-1 linux-zen 6.9.6.zen1-1 The sound device is reported with lsusb as `0db0:543d Micro Star International USB Audio` With default configuration, all seems well until hearing 5.1/7.1 channel audio. At this point it is realized that my 2.1 configuration is playing audio in surround mode and I'm missing virtually all of the most important sound. After researching for a while, I've found the following to hacky-workaround? the issue: ``` 90c90 < Regex "USB((0414:a0(0e|1[0124]))|(0b05:(19(84|9[69])|1a(16|2[07]|5[23c]|97|f1)))|(0db0:(005a|124b|151f|1feb|3130|36e7|4(19c|22d|240|88c)|62a4|6c[0c]9|70d3|7696|82c7|8af7|961e|a(073|228|47c|74b)|b202|d1d7|d6e7))|(26ce:0a0[68]))" --- > Regex "USB((0414:a0(0e|1[0124]))|(0b05:(19(84|9[69])|1a(16|2[07]|5[23c]|97|f1)))|(0db0:(005a|124b|151f|1feb|3130|36e7|4(19c|22d|240|88c)|543d|62a4|6c[0c]9|70d3|7696|82c7|8af7|961e|a(073|228|47c|74b)|b202|d1d7|d6e7))|(26ce:0a0[68]))" ``` This adds matching under ALC4080 for my 0db0:543d. After this I have 2.1 as well as the ability to select 5.1 or 7.1. I have patched the alsa-ucm-conf package locally with epoch to finalize the configuration. However, I do not know that this is the appropriate solution. Whether my sound device is mis-identified by ALSA/UCM, misrepresented by MSI? Something else? Please advise and perhaps this can be resolved in a way that benefits more than just myself.

[PATCH] ASoC: qcom: Adjust issues in case of DT error in asoc_qcom_lpass_cpu_platform_probe()
by Aleksandr Mishin 26 Jun '24

26 Jun '24

If IORESOURCE_MEM "lpass-rxtx-cdc-dma-lpm" or "lpass-va-cdc-dma-lpm" resources is not provided in Device Tree due to any error, platform_get_resource_byname() will return NULL which is later dereferenced. According to sound/qcom,lpass-cpu.yaml, these resources are provided, but DT can be broken due to any error. In such cases driver must be able to protect itself, since the DT is external data for the driver. Adjust this issues by adding NULL return check.

[PATCH 1/2] ASoC: codecs: lpass-macro: Gracefully handle unknown version
by Krzysztof Kozlowski 26 Jun '24

26 Jun '24

Qualcomm LPASS macro codec driver parses registers in order to detect version of the codec. It recognizes codecs v2.0 - v2.8, however we know that there are earlier versions and 'enum lpass_codec_version' has also v1.0, v1.1 and v1.2. If by any chance we run on unrecognized version, driver will use random value from the stack as the codec version. Fix it by mapping such cases to an enum of value 0: LPASS_CODEC_VERSION_UNKNOWN.

[PATCH 0/3] ASoC: codecs: lpass-wsa-macro: Add support for newer v2.5 version
by Krzysztof Kozlowski 26 Jun '24

26 Jun '24

Hi, LPASS codec v2.5 and newer have differences in registers which we did not implement so far. Lack of proper support is visible during playback: on SoCs with v2.6 (e.g. Qualcomm SM8550) only one speaker plays. Add missing bits for v2.5 and newer codecs. This is similar work to already merged: https://lore.kernel.org/all/20240612-lpass-codec-v25-v4-0-f63d3676dbc4@lina… No dependencies.

Virtual nodes created by UCM rules have the exact same nick, making them indistinguishable in KDE's audio applet
by GitHub issues - opened 25 Jun '24

25 Jun '24

alsa-project/alsa-ucm-conf issue #426 was opened from z411: Hello, Recently KDE Plasma's applet started using the node's nick to show the name of the device. The problem is that for audio interfaces that separate their inputs into virtual interfaces, they end up with something like this: ``` alsa.card_name = "Volt 2" device.profile.description = "Mono Input 1" node.description = "Volt 2 Mono Input 1" node.nick = "Volt 2" ``` ``` alsa.card_name = "Volt 2" device.profile.description = "Mono Input 2" node.description = "Volt 2 Mono Input 2" node.nick = "Volt 2" ``` Since they use the same nick, the end result is that we end up with an input list that looks like this: ![image](https://github.com/alsa-project/alsa-ucm-conf/assets/1988512/34e794ce-07ce-45b8-8be4-073dad24d339) Could the node nick be changed to reflect that this is a virtual device that refers to a different input from the same device? We already have an issue about this open in PipeWire and KDE issue trackers but we're not sure where this should be really fixed. Thanks.

We mark "MICBIAS1" and "MICBIAS2" with snd_soc_dapm_ignore_suspend() at es8326_enable_micbias(), and make "MICBIAS1" "MICBIAS2" active with snd_soc_dapm_force_enable_pin_unlocked(). But when the device enter suspend, the codec can't enter suspend.

[RESEND PATCH] ALSA: dmaengine_pcm: terminate dmaengine before synchronize
by Shengjiu Wang 25 Jun '24

25 Jun '24

When dmaengine supports pause function, in suspend state, dmaengine_pause() is called instead of dmaengine_terminate_async(), In end of playback stream, the runtime->state will go to SNDRV_PCM_STATE_DRAINING, if system suspend & resume happen at this time, application will not resume playback stream, the stream will be closed directly, the dmaengine_terminate_async() will not be called before the dmaengine_synchronize(), which violates the call sequence for dmaengine_synchronize(). This behavior also happens for capture streams, but there is no SNDRV_PCM_STATE_DRAINING state for capture. So use dmaengine_tx_status() to check the DMA status if the status is DMA_PAUSED, then call dmaengine_terminate_async() to terminate dmaengine before dmaengine_synchronize().

[PATCH v3 0/2] tlv320adc3xxx: Allow MICBIAS pins to be used as GPOs
by Ricard Wanderlof 23 Jun '24

23 Jun '24

In some cases, depending on system design, the MICBIAS pins on the chip are not needed as such, but a couple of extra GPIO pins would be useful. This patch allows the MICBIAS pins to be configured in the device tree as general purpose output pins, controlled via the GPIO framework. Owing to their originally intended purpose there are some limitations: when the MICBIAS pins are deactivated, they will float, so will likely need a pulldown in many applications. When activated, they will assume the voltage specified by the micbias1-vg and micbias2-vg properties, respectively, meaning that the resulting output voltage will be 2.0 V, 2.5 V or AVDD .

[PATCH 0/8] iio: adc: dfsdm: add scaling support
by Olivier Moysan 23 Jun '24

23 Jun '24

The aim of this serie is to add scaling support to STM32 DFSDM peripheral in the analog context. The DFSDM currently operates as a consumer of IIO channels provided by a generic SD modulator. As previously discussed in RFC [1], this topology is not suitable for implementing scaling. This series brings the integration of the DFSDM driver with the new IIO backend framework [2], enabling the DFSDM IIO device to offer scaling feature based on reference voltage data obtained from the IIO SD modulator backend. This generic SD modulator backend takes the place of the former SD modulator, used with legacy implementation. The DFSDM driver has been updated to adopt the generic ADC channel binding [3]. The reasons for this include: - Reducing the use of proprietary properties - Simplifying the coexistence of legacy and new backend bindings - Prepare the support of the MDF peripheral on STM32MP25 SoC Backward compatibility is maintained through legacy support. This series extends the backend framework with the following APIs (which may need further refinement): - read_raw: This API is intented to retrieve the voltage information from the backend. It is based on IIO read_raw API, but maybe we need a more specialized API here. - iio_backend_disable / iio_backend_enable: backend enable/disable to be used for PM management - devm_iio_backend_subnode_get Intended for parsing DT subnodes to allow generic channel binding support, as generic channel DT nodes are not populated as devices. Ideally, a single API would be better, but I could not identify a suitable alternative that doesn't affect the existing API (devm_iio_backend_get).

[PATCH v4 00/40] lib/find: add atomic find_bit() primitives
by Yury Norov 20 Jun '24

20 Jun '24

--- This v4 moves new API to separate headers, as adding stuff to find.h concerns people, particularly Linus. It also adds few more conversions alongside other cosmetic changes. See full changelog below. --- Add helpers around test_and_{set,clear}_bit() to allow searching for clear or set bits and flipping them atomically. Using atomic search primitives allows to implement lockless bitmap handling where only individual bits are touched by concurrent processes, and where people now have to protect their bitmaps to search for a free or set bit due to the lack of atomic searching routines. The typical lock-protected bit allocation may look like this: unsigned long alloc_bit() { unsigned long bit; spin_lock(bitmap_lock); bit = find_first_zero_bit(bitmap, nbits); if (bit < nbits) __set_bit(bit, bitmap); spin_unlock(bitmap_lock); return bit; } void free_bit(unsigned long bit) { spin_lock(bitmap_lock); __clear_bit(bit, bitmap); spin_unlock(bitmap_lock); } Now with atomic find_and_set_bit(), the above can be implemented lockless, directly by using it and atomic clear_bit(). Patches 36-40 do this in few places in the kernel where the transition is clear. There is likely more candidates for refactoring. The other important case is when people opencode atomic search or atomic traverse on the maps with the patterns looking like: for (idx = 0; idx < nbits; idx++) if (test_and_clear_bit(idx, bitmap)) do_something(idx); Or like this: do { bit = find_first_bit(bitmap, nbits); if (bit >= nbits) return nbits; } while (!test_and_clear_bit(bit, bitmap)); return bit; In both cases, the opencoded loop may be converted to a single function or iterator call. Correspondingly: for_each_test_and_clear_bit(idx, bitmap, nbits) do_something(idx); Or: return find_and_clear_bit(bitmap, nbits); Obviously, the less routine code people have to write themself, the less probability to make a mistake. The patch #33 fixes one such mistake. The new API is not only a handy helpers - it also resolves a non-trivial issue of using non-atomic find_bit() together with atomic test_and_{set,clear)_bit(). The trick is that find_bit() implies that the bitmap is a regular non-volatile piece of memory, and compiler is allowed to use such optimization techniques like re-fetching memory instead of caching it. For example, find_first_bit() is implemented like: for (idx = 0; idx * BITS_PER_LONG < sz; idx++) { val = addr[idx]; if (val) { sz = min(idx * BITS_PER_LONG + __ffs(val), sz); break; } } On register-memory architectures, like x86, compiler may decide to access memory twice - first time to compare against 0, and second time to fetch its value to pass it to __ffs(). When running find_first_bit() on volatile memory, the memory may get changed in-between, and for instance, it may lead to passing 0 to __ffs(), which is an undefined behaviour. This is a potentially dangerous call. find_and_clear_bit() as a wrapper around test_and_clear_bit() naturally treats underlying bitmap as a volatile memory and prevents compiler from such optimizations. Now that KCSAN is catching exactly this type of situations and warns on undercover memory modifications. We can use it to reveal improper usage of find_bit(), and convert it to atomic find_and_*_bit() as appropriate. In some cases concurrent operations with plain find_bit() are acceptable. For example: - two threads running find_*_bit(): safe wrt ffs(0) and returns correct value, because underlying bitmap is unchanged; - find_next_bit() in parallel with set or clear_bit(), when modifying a bit prior to the start bit to search: safe and correct; - find_first_bit() in parallel with set_bit(): safe, but may return wrong bit number; - find_first_zero_bit() in parallel with clear_bit(): same as above. In last 2 cases find_bit() may not return a correct bit number, but it may be OK if caller requires any (not exactly the first) set or clear bit, correspondingly. In such cases, KCSAN may be safely silenced with data_race(). But in most cases where KCSAN detects concurrency we should carefully review the code and likely protect critical sections or switch to atomic find_and_bit(), as appropriate. This patch adds the following atomic primitives: find_and_set_bit(addr, nbits); find_and_set_next_bit(addr, nbits, start); ... Here find_and_{set,clear} part refers to the corresponding test_and_{set,clear}_bit function. Suffixes like _wrap or _lock derive their semantics from corresponding find() or test() functions. For brevity, the naming omits the fact that we search for zero bit in find_and_set, and correspondingly search for set bit in find_and_clear functions. The patch also adds iterators with atomic semantics, like for_each_test_and_set_bit(). Here, the naming rule is to simply prefix corresponding atomic operation with 'for_each'. This series is not aimed on performance, but some performance implications are considered. In [1] Jan reported 2% slowdown in a single-thread search test when switching find_bit() function to treat bitmaps as volatile arrays. On the other hand, kernel robot in the same thread reported +3.7% to the performance of will-it-scale.per_thread_ops test. Assuming that our compilers are sane and generate better code against properly annotated data, the above discrepancy doesn't look weird. When running on non-volatile bitmaps, plain find_bit() outperforms atomic find_and_bit(), and vice-versa. So, all users of find_bit() API, where heavy concurrency is expected, are encouraged to switch to atomic find_and_bit() as appropriate. The 1st patch of this series adds atomic find_and_bit() API, 2nd adds a basic test for new API, and all the following patches spread it over the kernel.

[PATCHv5 9/9] ARM: dts: imx6: update spdif sound card node properties
by Elinor Montmasson 20 Jun '24

20 Jun '24

Following merge of imx-spdif driver into fsl-asoc-card: * update properties to match those used by fsl-asoc-card. * S/PDIF in/out dummy codecs must now be declared explicitly, add and use them. These modifications were tested only on an imx8mn-evk board.

[PATCHv5 5/9] ASoC: fsl-asoc-card: merge spdif support from imx-spdif.c
by Elinor Montmasson 20 Jun '24

20 Jun '24

The imx-spdif machine driver creates audio card to directly use an S/PDIF device. However, it doesn't support interacting with an ASRC. fsl-asoc-card already has the support to create audio card which can use the ASRC. Merge the S/PDIF support from imx-spdif into fsl-asoc-card to extend the support of S/PDIF audio card with the use of ASRC devices. It also substitutes the use of the dummy codec in imx-spdif with the existing spdif_transmitter and spdif_receiver codec drivers.

[PATCHv5 4/9] ASoC: fsl-asoc-card: add compatibility to use 2 codecs in dai-links
by Elinor Montmasson 20 Jun '24

20 Jun '24

Adapt the driver to work with configurations using two codecs or more. Modify fsl_asoc_card_probe() to handle use cases where 2 codecs are given in the device tree. This will be needed to add support for the SPDIF. Use cases using one codec will ignore any given codecs other than the first.

[PATCHv5 3/9] ASoC: fsl-asoc-card: add second dai link component for codecs
by Elinor Montmasson 20 Jun '24

20 Jun '24

Add a second dai link component for codecs that will be used for use cases with 2 codecs. It is needed for future integration of the SPDIF support, which will use spdif_receiver and spdif_transmitter drivers. To prevent deferring in use cases using only one codec, also set by default the number of codecs to 1 for the relevant dai links.

[PATCHv5 1/9] ASoC: fsl-asoc-card: set priv->pdev before using it
by Elinor Montmasson 20 Jun '24

20 Jun '24

priv->pdev pointer was set after being used in fsl_asoc_card_audmux_init(). Move this assignment at the start of the probe function, so sub-functions can correctly use pdev through priv. fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the dev struct, used with dev_err macros. As priv is zero-initialised, there would be a NULL pointer dereference. Note that if priv->dev is dereferenced before assignment but never used, for example if there is no error to be printed, the driver won't crash probably due to compiler optimisations.

[PATCH] ALSA: hda: cs35l56: Select SERIAL_MULTI_INSTANTIATE
by Simon Trimmer 20 Jun '24

20 Jun '24

The ACPI IDs used in the CS35L56 HDA drivers are all handled by the serial multi-instantiate driver which starts multiple Linux device instances from a single ACPI Device() node. As serial multi-instantiate is not an optional part of the system add it as a dependency in Kconfig so that it is not overlooked.

ALSA volume control ignored for "4c4a:4155 Jieli Technology USB Composite Device"
by GitHub issues - opened 20 Jun '24

20 Jun '24

alsa-project/alsa-lib issue #401 was opened from davidmcnabnz: I just purchased a generic USB audio interface, which shows up in `lsusb` as: ``` 4c4a:4155 Jieli Technology USB Composite Device ``` The device on the whole seems to _simply just work_. But the level control for the stereo capture seems to be completely ignored, both in `alsamixer` and `pavucontrol`. My setup is Debian GNU/Linux 12 (bookworm), standard apt including contrib. General stack is wireplumber and pipewire, implementing JACK via pw-jack and pipewire-pulse. This is working very well for my music work. Lastly, below is a paste of my currently installed packages relevant to ALSA and JACK. Grateful if anyone can advise.

[PATCH v6 0/7] ASoC: codecs: wcd937x: add wcd937x audio codec support
by Mohammad Rafi Shaik 19 Jun '24

19 Jun '24

This patchset adds support for Qualcomm WCD9370/WCD9375 codec. Qualcomm WCD9370/WCD9375 Codec is a standalone Hi-Fi audio codec IC connected over SoundWire. This device has two SoundWire devices, RX and TX respectively supporting 3 x ADCs, ClassH, Ear, Aux PA, 2xHPH, 6 DMICs and MBHC. For codec driver to be functional it would need both tx and rx Soundwire devices to be up and this is taken care by using device component framework and device-links are used to ensure proper pm dependencies. Ex tx does not enter suspend before rx or codec is suspended. This patchset along with other SoundWire patches on the list have been tested on QCM6490 IDP device. Changes since v5: - Remove the string compare in MIC BIAS widget settings as suggested by Srinivas Kandagatla - Fixed Unbalanced pm_runtime_enable! in wcd937x-sdw soundwire slave. Changes since v4: - Removed volatile/read-only registers from defaults list - Added wcd939x_volatile_register() with only volatile registers - Added a wcd939x_readable_register() with read-only and read-write registers, so cache does it's job - Fixed Spurious events for mixer controls and validated with mixer selftest tool - Used TLV instead of enum for ear_pa_gain mixer control - Used enum constraints instead of OneOf in dt-binding patch - Added vdd-px supply property as non optional in dt-binding patch - Reworked and done driver cleanup Changes since v3: - Fixed dt binding check errors. - Added constraints on values in v4-0001 binding patch as suggested by Krzysztof - Change the patch sequence soundwire driver first then codec driver - Added missing .remove soundwire driver function - Reworked and done driver cleanup Changes since v2: - Used common qcom,wcd93xx-common.yaml. removed duplicate properties. - Merged bindings patches "v2-0001" and "v2-0003" in single patch for easy review. - Fixed dt binding check errors. - Added missing "qcom,wcd9375-codec" in v3-0001 dt binding patch. - Added constraints on values in v3-0001 binding patch as suggested by Krzysztof - Fix the typo mistake in v2 cover letter Changes since v1: - Split the patch per driver for easier review as suggested by Krzysztof - Used devm_gpiod_get api to get reset gpio as suggested by Krzysztof Prasad Kumpatla (7): ASoC: dt-bindings: document wcd937x Audio Codec ASoC: codecs: wcd937x-sdw: add SoundWire driver ASoC: codecs: wcd937x: add wcd937x codec driver ASoC: codecs: wcd937x: add basic controls ASoC: codecs: wcd937x: add playback dapm widgets ASoC: codecs: wcd937x: add capture dapm widgets ASoC: codecs: wcd937x: add audio routing and Kconfig .../bindings/sound/qcom,wcd937x-sdw.yaml | 91 + .../bindings/sound/qcom,wcd937x.yaml | 82 + sound/soc/codecs/Kconfig | 20 + sound/soc/codecs/Makefile | 7 + sound/soc/codecs/wcd937x-sdw.c | 1136 +++++++ sound/soc/codecs/wcd937x.c | 3011 +++++++++++++++++ sound/soc/codecs/wcd937x.h | 653 ++++ 7 files changed, 5000 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/qcom,wcd937x-sdw.yaml create mode 100644 Documentation/devicetree/bindings/sound/qcom,wcd937x.yaml create mode 100644 sound/soc/codecs/wcd937x-sdw.c create mode 100644 sound/soc/codecs/wcd937x.c create mode 100644 sound/soc/codecs/wcd937x.h base-commit: d35b2284e966c0bef3e2182a5c5ea02177dd32e4 -- 2.25.1

[PATCH] ASoC: cs35l56: Accept values greater than 0 as IRQ numbers
by Simon Trimmer 19 Jun '24

19 Jun '24

IRQ lookup functions such as those in ACPI can return error values when an IRQ is not defined. The i2c core driver converts the error codes to a value of 0 and the SPI bus driver passes them unaltered to client device drivers. The cs35l56 driver should only accept positive non-zero values as IRQ numbers.

aloop driver introducing glitches
by noman pouigt 18 Jun '24

18 Jun '24

Hello Folks, I wanted to use aloop driver to dump playback audio data to a file in userspace for debugging without data being sent to hardware (just as a debug feature for future use). Command flow is this: 1. aloop capture device is started using below command first: "arec -D hw:0,1 /data/rec.wav &" 2. using aplay, userspace sends the playback data. "aplay -D hw:0,0 /data/test.wav" Using jiffies. Wondering if changing rate_shift (don't know what is that for) will help? However, even in this simple setup I can see aloop driver is corrupting the data and sinetone sent from playback has glitches. I have tried different period sizes as well but nothing worked. Wondering if this is by design i.e. if the aloop driver shouldn't be used for this purpose? Any debug steps will be highly appreciated. Thanks for your help,

[PATCH] ALSA: hda: cs35l56: Perform firmware download in the background
by Simon Trimmer 18 Jun '24

18 Jun '24

It is possible that during system boot when there multiple devices attempting simultaneous initialization on a slow control bus the download of firmware and tuning data may take a user perceivable amount of time (a slow I2C bus with 4 amps this work could take over 2 seconds). Adopt a pattern used in the ASoC driver and perform this activity in a background thread so that interactive performance is not impaired.

[PATCH v5 resend 0/4] ASoC: grace time for DPCM cleanup
by Kuninori Morimoto 17 Jun '24

17 Jun '24

Hi Mark, Pierre-Louis, Jerome Cc each ASoC driver maintainer 2 weeks past. This is resend of v5 of DPCM cleanup As we discussed in [1], we don't need to use dpcm_playback/capture flag, so we remove it. But we have been using it for 10 years, some driver might get damage. The most likely case is that the device/driver can use both playback/capture, but have only one flag, and not using xxx_only flag. [1/3] patch indicates warning in such case. These adds grace time for DPCM cleanup. I'm not sure when dpcm_xxx will be removed, and Codec check bypass will be error, but maybe v6.11 or v6.12 ? Please check each driver by that time. Previous patch-set try to check both CPU and Codec in DPCM, but we noticed that there are some special DAI which we can't handle today [2]. So I will escape it in this patch-set.

[PATCH] slimbus: Fix struct and documentation alignment in stream.c
by Amit Vadhavana 16 Jun '24

16 Jun '24

The placement of the `segdist_codes` array documentation was corrected to conform with kernel documentation guidelines. The `@segdist_codes` was placed incorrectly within the struct `segdist_code` documentation block, which led to a potential misinterpretation of the code structure. The `segdist_codes` array documentation was moved outside the struct block, and a separate comment block was provided for it. This change ensures that clarity and proper alignment with kernel documentation standards are maintained. A kernel-doc warning was addressed: ./drivers/slimbus/stream.c:49: warning: Excess struct member 'segdist_codes' description in 'segdist_code' Signed-off-by: Amit Vadhavana <av2082000(a)gmail.com> --- drivers/slimbus/stream.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/slimbus/stream.c b/drivers/slimbus/stream.c index 1d6b38657917..62661211a409 100644 --- a/drivers/slimbus/stream.c +++ b/drivers/slimbus/stream.c @@ -18,7 +18,6 @@ * and the first slot of the next consecutive Segment. * @segdist_code: Segment Distribution Code SD[11:0] * @seg_offset_mask: Segment offset mask in SD[11:0] - * @segdist_codes: List of all possible Segmet Distribution codes. */ static const struct segdist_code { int ratem; @@ -26,7 +25,10 @@ static const struct segdist_code { int segdist_code; u32 seg_offset_mask; -} segdist_codes[] = { +}; + +/* segdist_codes - List of all possible Segment Distribution codes. */ +static const struct segdist_code segdist_codes[] = { {1, 1536, 0x200, 0xdff}, {2, 768, 0x100, 0xcff}, {4, 384, 0x080, 0xc7f}, -- 2.25.1

[PATCH v2] ASoC: cs35l56: Disconnect ASP1 TX sources when ASP1 DAI is hooked up
by Richard Fitzgerald 15 Jun '24

15 Jun '24

If the ASP1 DAI is hooked up by the machine driver the ASP TX mixer sources should be initialized to disconnected. There aren't currently any available products using the ASP so this doesn't affect any existing systems. The cs35l56 does not have any fixed default for the mixer source registers. When the cs35l56 boots, its firmware patches these registers to setup a system-specific routing; this is so that Windows can use generic SDCA drivers instead of needing knowledge of chip-specific registers. The setup varies between end-products, which each have customized firmware, and so the default register state varies between end-products. It can also change if the firmware on an end-product is upgraded - for example if a change was needed to the routing for Windows use-cases. It must be emphasized that the settings applied by the firmware are not internal magic tuning; they are statically implementing use-case setup that on Linux would be done via ALSA controls. The driver is currently syncing the mixer controls with whatever initial state the firmware wrote to the registers, so that they report the actual audio routing. But if the ASP DAI is hooked up this can create a powered-up DAPM graph without anything intentionally setting up a path. This can lead to parts of the audio system powering up unexpectedly. For example when cs35l56 is connected to cs42l43 using a codec-codec link, this can create a complete DAPM graph which then powers-up cs42l43. But the cs42l43 can only be clocked from its SoundWire bus so this causes a bunch of errors in the kernel log where cs42l43 is unexpectedly powered-up without a clock. If the host is taking ownership of the ASP (either directly or as a codec-to-codec link) there is no need to keep the mixer settings that the firmware wrote. The driver has ALSA controls for setting these using standard Linux mechanisms. So if the machine driver hooks up the ASP the ASP mixers are initialized to "None" (no input). This prevents unintended DAPM-graph power-ups, and means the initial state of the mixers is always going to be None. Since the initial state of the mixers can vary from system to system and potentially between firmware upgrades, no use-case manager can currently assume that cs35l56 has a known initial state. The firmware could just as easily default them to "None" as to any input source. So defaulting them to "None" in the driver is not increasing the entropy of the system.

[PATCH] ASoC: q6apm-lpass-dai: close graph on prepare errors
by Srinivas Kandagatla 15 Jun '24

15 Jun '24

There is an issue around with error handling and graph management with the exising code, none of the error paths close the graph, which result in leaving the loaded graph in dsp, however the driver thinks otherwise. This can have a nasty side effect specially when we try to load the same graph to dsp, dsp returns error which leaves the board with no sound and requires restart. Fix this by properly closing the graph when we hit errors between open and close.

[PATCH v7 0/1] Add tas2781 driver for SPI.
by Baojun Xu 13 Jun '24

13 Jun '24

This patch was used to add TAS2781 devices on SPI support in sound/pci/hda. It use ACPI node descript about parameters of TAS2781 on SPI, it like: Scope (_SB.PC00.SPI0) { Device (GSPK) { Name (_HID, "TXNW2781") // _HID: Hardware ID Method (_CRS, 0, NotSerialized) { Name (RBUF, ResourceTemplate () { SpiSerialBusV2 (...) SpiSerialBusV2 (...) } } } } And in platform/x86/serial-multi-instantiate.c, those spi devices will be added into system as a single SPI device, so TAS2781 SPI driver will probe twice for every single SPI device. And driver will also parser mono DSP firmware binary and RCA binary for itself.

Originally reported here: https://github.com/thesofproject/avs-topology-xml/issues/22#issuecomment-21… There is various level of failure there, first of all when topology loads routes, it points directly into FW file, but it may be freed after topology load. After fixing the above, when avs driver parses topology it should allocate its own memory, as target strings can be shorter than needed. Also clean up soc_tplg_dapm_graph_elems_load() a bit.

[PATCH] ASoC: cs35l56: Disconnect ASP1 TX sources when ASP1 DAI is hooked up
by Richard Fitzgerald 12 Jun '24

12 Jun '24

If the ASP1 DAI is hooked up by the machine driver the ASP TX mixer sources should be initialized to disconnected. The silicon default is for the mixer source registers to default to a collection of monitoring sources. The problem with this is that it causes the DAPM graph to initialize with the capture path connected to a valid source widget, even though nothing setup a path. When the ASP DAI is connected as a codec-to-codec link this will cause the other codec to power-up even though nothing is using it.

[PATCH v5 0/7] ASoC: codecs: wcd937x: add wcd937x audio codec support
by Mohammad Rafi Shaik 11 Jun '24

11 Jun '24

This patchset adds support for Qualcomm WCD9370/WCD9375 codec. Qualcomm WCD9370/WCD9375 Codec is a standalone Hi-Fi audio codec IC connected over SoundWire. This device has two SoundWire devices, RX and TX respectively supporting 3 x ADCs, ClassH, Ear, Aux PA, 2xHPH, 6 DMICs and MBHC. For codec driver to be functional it would need both tx and rx Soundwire devices to be up and this is taken care by using device component framework and device-links are used to ensure proper pm dependencies. Ex tx does not enter suspend before rx or codec is suspended. This patchset along with other SoundWire patches on the list have been tested on QCM6490 IDP device. Changes since v4: - Removed volatile/read-only registers from defaults list - Added wcd939x_volatile_register() with only volatile registers - Added a wcd939x_readable_register() with read-only and read-write registers, so cache does it's job - Fixed Spurious events for mixer controls and validated with mixer selftest tool - Used TLV instead of enum for ear_pa_gain mixer control - Used enum constraints instead of OneOf in dt-binding patch - Added vdd-px supply property as non optional in dt-binding patch - Reworked and done driver cleanup Changes since v3: - Fixed dt binding check errors. - Added constraints on values in v4-0001 binding patch as suggested by Krzysztof - Change the patch sequence soundwire driver first then codec driver - Added missing .remove soundwire driver function - Reworked and done driver cleanup Changes since v2: - Used common qcom,wcd93xx-common.yaml. removed duplicate properties. - Merged bindings patches "v2-0001" and "v2-0003" in single patch for easy review. - Fixed dt binding check errors. - Added missing "qcom,wcd9375-codec" in v3-0001 dt binding patch. - Added constraints on values in v3-0001 binding patch as suggested by Krzysztof - Fix the typo mistake in v2 cover letter Changes since v1: - Split the patch per driver for easier review as suggested by Krzysztof - Used devm_gpiod_get api to get reset gpio as suggested by Krzysztof Prasad Kumpatla (7): ASoC: dt-bindings: document wcd937x Audio Codec ASoC: codecs: wcd937x-sdw: add SoundWire driver ASoC: codecs: wcd937x: add wcd937x codec driver ASoC: codecs: wcd937x: add basic controls ASoC: codecs: wcd937x: add playback dapm widgets ASoC: codecs: wcd937x: add capture dapm widgets ASoC: codecs: wcd937x: add audio routing and Kconfig .../bindings/sound/qcom,wcd937x-sdw.yaml | 91 + .../bindings/sound/qcom,wcd937x.yaml | 82 + sound/soc/codecs/Kconfig | 20 + sound/soc/codecs/Makefile | 7 + sound/soc/codecs/wcd937x-sdw.c | 1139 +++++++ sound/soc/codecs/wcd937x.c | 3029 +++++++++++++++++ sound/soc/codecs/wcd937x.h | 653 ++++ 7 files changed, 5021 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/qcom,wcd937x-sdw.yaml create mode 100644 Documentation/devicetree/bindings/sound/qcom,wcd937x.yaml create mode 100644 sound/soc/codecs/wcd937x-sdw.c create mode 100644 sound/soc/codecs/wcd937x.c create mode 100644 sound/soc/codecs/wcd937x.h base-commit: 124cfbcd6d185d4f50be02d5f5afe61578916773 -- 2.25.1

[PATCH 0/3] ACPI/ALSA/soundwire: add acpi_get_local_u64_address() helper
by Pierre-Louis Bossart 11 Jun '24

11 Jun '24

The acpi_get_local_address() helper assumes a 32-bit ADR is used. If we want to use this helper for SoundWire/SDCA ASoC codecs, we need an extension where the native 64-bits are used. This patchset suggests a new helper, acpi_get_local_address() may be renamed if desired in a folow-up patch. The path of least resistance would be to merge this patchset in the ASoC tree, since I have additional changes for ASoC/SDCA (SoundWire Device Class) that depend on the new helper.

[PATCH v22 00/38] Introduce QC USB SND audio offloading support
by Wesley Cheng 11 Jun '24

11 Jun '24

Requesting to see if we can get some Acked-By tags, and merge on usb-next. Several Qualcomm based chipsets can support USB audio offloading to a dedicated audio DSP, which can take over issuing transfers to the USB host controller. The intention is to reduce the load on the main processors in the SoC, and allow them to be placed into lower power modes. There are several parts to this design: 1. Adding ASoC binding layer 2. Create a USB backend for Q6DSP 3. Introduce XHCI interrupter support 4. Create vendor ops for the USB SND driver USB | ASoC -------------------------------------------------------------------- | _________________________ | |sm8250 platform card | | |_________________________| | | | | ___V____ ____V____ | |Q6USB | |Q6AFE | | |"codec" | |"cpu" | | |________| |_________| | ^ ^ ^ | | |________| | ___V____ | | |SOC-USB | | ________ ________ | | | |USB SND |<--->|QC offld|<------------>|________| | |(card.c)| | |<---------- | |________| |________|___ | | | ^ ^ | | | ____________V_________ | | | | | |APR/GLINK | __ V_______________V_____ | | | |______________________| |USB SND (endpoint.c) | | | | ^ |_________________________| | | | | ^ | | | ___________V___________ | | | |->|audio DSP | ___________V_____________ | | |_______________________| |XHCI HCD |<- | |_________________________| | Adding ASoC binding layer: soc-usb: Intention is to treat a USB port similar to a headphone jack. The port is always present on the device, but cable/pin status can be enabled/disabled. Expose mechanisms for USB backend ASoC drivers to communicate with USB SND. Create a USB backend for Q6DSP: q6usb: Basic backend driver that will be responsible for maintaining the resources needed to initiate a playback stream using the Q6DSP. Will be the entity that checks to make sure the connected USB audio device supports the requested PCM format. If it does not, the PCM open call will fail, and userpsace ALSA can take action accordingly. Introduce XHCI interrupter support: XHCI HCD supports multiple interrupters, which allows for events to be routed to different event rings. This is determined by "Interrupter Target" field specified in Section "6.4.1.1 Normal TRB" of the XHCI specification. Events in the offloading case will be routed to an event ring that is assigned to the audio DSP. Create vendor ops for the USB SND driver: qc_audio_offload: This particular driver has several components associated with it: - QMI stream request handler - XHCI interrupter and resource management - audio DSP memory management When the audio DSP wants to enable a playback stream, the request is first received by the ASoC platform sound card. Depending on the selected route, ASoC will bring up the individual DAIs in the path. The Q6USB backend DAI will send an AFE port start command (with enabling the USB playback path), and the audio DSP will handle the request accordingly. Part of the AFE USB port start handling will have an exchange of control messages using the QMI protocol. The qc_audio_offload driver will populate the buffer information: - Event ring base address - EP transfer ring base address and pass it along to the audio DSP. All endpoint management will now be handed over to the DSP, and the main processor is not involved in transfers. Overall, implementing this feature will still expose separate sound card and PCM devices for both the platorm card and USB audio device: 0 [SM8250MTPWCD938]: sm8250 - SM8250-MTP-WCD9380-WSA8810-VA-D SM8250-MTP-WCD9380-WSA8810-VA-DMIC 1 [Audio ]: USB-Audio - USB Audio Generic USB Audio at usb-xhci-hcd.1.auto-1.4, high speed This is to ensure that userspace ALSA entities can decide which route to take when executing the audio playback. In the above, if card#1 is selected, then USB audio data will take the legacy path over the USB PCM drivers, etc... This feature was validated using: - tinymix: set/enable the multimedia path to route to USB backend - tinyplay: issue playback on platform card Changelog -------------------------------------------- Changes in v22: - Removed components tag for the ASoC platform card, as the USB SND kcontrol for notifying userspace of offload capable card achieves similar results. - Due to the above, had to remove the review-by tag for the RST documentation, as changes were made to remove the components tag section. - Took in feedback to make the SOC USB add/remove ports void. - Fixed an issue w/ the USB SND kcontrol management for devices that have multi UAC interfaces. (would attempt to create the kcontrol more than once) - Modified SOC USB card and PCM index select to be based off the num_supported streams that is specified by the USB BE DAI. - Modified comments on selecting the latest USB headset for offloading. Changes in v21: - Added an offload jack disable path from the ASoC platform driver and SOC USB. - Refactored some of the existing SOC USB context look up APIs and created some new helpers to search for the USB context. - Renamed snd_soc_usb_find_format to snd_soc_usb_find_supported_format - Removed some XHCI sideband calls that would allow clients to actually enable the IRQ line associated w/ the secondary interrupter. This is removed because there are other dependencies that are required for that to happen, which are not covered as part of this series, and to avoid confusion. - Due to the above, removed the need to export IMOD setting, and enable/disable interrupter APIs. Changes in v20: - Fixed up some formatting changes pointed out in the usb.rst - Added SB null check during XHCI sideband unregister in case caller passes improper argument (xhci_sideband_unregister()) Changes in v19: - Rebased to usb-next to account for some new changes in dependent drivers. Changes in v18: - Rebased to usb-next, which merged in part of the series. Removed these patches. - Reworked Kconfigs for the ASoC USB related components from QCOM Q6DSP drivers to keep dependencies in place for SoC USB and USB SND. - Removed the repurposing of the stop ep sync API into existing XHCI operations. This will be solely used by the XHCI sideband for now. Changes in v17: - Fixed an issue where one patch was squashed into another. - Re-added some kconfig checks for helpers exposed in USB SND for the soc usb driver, after running different kconfigs. Changes in v16: - Modified some code layer dependencies so that soc usb can be split as a separate module. - Split the kcontrols from ASoC QCOM common layer into a separate driver - Reworked SOC USB kcontrols for controlling card + pcm offload routing and status so that there are individual controls for card and pcm devices. - Added a kcontrol remove API in SOC USB to remove the controls on the fly. This required to add some kcontrol management to SOC USB. - Removed the disconnect work and workqueue for the QC USB offload as it is not required, since QMI interface driver ensures events are handled in its own WQ. Changes in v15: - Removed some already merged XHCI changes - Separated SOC USB driver from being always compiled into SOC core. Now configurable from kconfig. - Fixed up ASoC kcontrol naming to fit guidelines. - Removed some unnecessary dummy ifdefs. - Moved usb snd offload capable kcontrol to be initialized by the platform offloading driver. Changes in v14: - Cleaned up some USB SND related feedback: - Renamed SNDUSB OFFLD playback available --> USB offload capable card - Fixed locking while checking if stream is in use - Replaced some mutex pairs with guard(mutex) Changes in v13: - Pulled in secondary/primary interrupter rework from Mathias from: https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/drivers… - Did some cleanup and commit message updates, and tested on current code base. - Added mutex locking to xhci sideband to help prevent any race conditions, esp. for when accessing shared references. - Addresed concerns from Hillf about gfp_flags and locking used in qc_usb_audio_offload. - Rebased onto usb-next Changes in v12: - Updated copyright year to 2024. Happy new years! - Fixed newline format on mixer offload driver. Changes in v11: - Modified QMI format structures to be const Changes in v10: - Added new mixer for exposing kcontrol for sound card created by USB SND. This allows for applications to know which platform sound card has offload support. Will return the card number. - Broke down and cleaned up some functions/APIs within qc_audio_offload driver. - Exported xhci_initialize_ring_info(), and modified XHCI makefile to allow for the XHCI sideband to exist as a module. - Reworked the jack registration and moved it to the QCOM platform card driver, ie sm8250. - Added an SOC USB API to fetch a standard component tag that can be appended to the platform sound card. Added this tag to sm8250 if any USB path exists within the DT node. - Moved kcontrols that existed in the Q6USB driver, and made it a bit more generic, so that naming can be standardized across solutions. SOC USB is now responsible for creation of these kcontrols. - Added a SOC USB RST document explaining some code flows and implementation details so that other vendors can utilize the framework. - Addressed a case where USB device connection events are lost if usb offload driver (qc_audio_offload) is not probed when everything else has been initialized, ie USB SND, SOC USB and ASoC sound card. Add a rediscover device call during module init, to ensure that connection events will be propagated. - Rebased to usb-next. Changes in v9: - Fixed the dt binding check issue with regards to num-hc-interrupters. Changes in v8: - Cleaned up snd_soc_usb_find_priv_data() based on Mark's feedback. Removed some of the duplicate looping code that was present on previous patches. Also renamed the API. - Integrated Mathias' suggestions on his new sideband changes: https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/?h=feat… - Addressed some of Mathias' fixme tags, such as: - Resetting transfer ring dequeue/enqueue pointers - Issuing stop endpoint command during ep removal - Reset ERDP properly to first segment ring during interrupter removal. (this is currently just being cleared to 0, but should be pointing to a valid segment if controller is still running. Changes in v7: - Fixed dt check error for q6usb bindings - Updated q6usb property from qcom,usb-audio-intr-num --> qcom,usb-audio-intr-idx - Removed separate DWC3 HC interrupters num property, and place limits to XHCI one. - Modified xhci_ring_to_sgtable() to use assigned IOVA/DMA address to fetch pages, as it is not ensured event ring allocated is always done in the vmalloc range. Changes in v6: - Fixed limits and description on several DT bindings (XHCI and Q6USB) - Fixed patch subjects to follow other ALSA/ASoC notations. USB SND - Addressed devices which expose multiple audio (UAC) interfaces. These devices will create a single USB sound card with multiple audio streams, and receive multiple interface probe routines. QC offload was not properly considering cases with multiple probe calls. - Renamed offload module name and kconfig to fit within the SND domain. - Renamed attach/detach endpoint API to keep the hw_params notation. Changes in v5: - Removed some unnescessary files that were included - Fixed some typos mentioned - Addressed dt-binding issues and added hc-interrupters definition to usb-xhci.yaml XHCI: - Moved secondary skip events API to xhci-ring and updated implementation - Utilized existing XHCI APIs, such as inc_deq and xhci_update_erst_dequeue() USB SND - Renamed and reworked the APIs in "sound: usb: Export USB SND APIs for modules" patch to include suggestions to utilize snd_usb_hw_params/free and to avoid generic naming. - Added a resume_cb() op for completion sake. - Addressed some locking concerns with regards to when registering for platform hooks. - Added routine to disconnect all offloaded devices during module unbind. ASoC - Replaced individual PCM parameter arguments in snd_soc_usb_connect() with new snd_soc_usb_device structure to pass along PCM info. - Modified snd_jack set report to notify HEADPHONE event, as we do not support record path. Changes in v4: - Rebased to xhci/for-usb-next - Addressed some dt-bindings comments XHCI: - Pulled in latest changes from Mathias' feature_interrupters branch: https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/?h=feat… - Fixed commit text and signage for the XHCI sideband/interrupter related changes - Added some logic to address the FIXME tags mentioned throughout the commits, such as handling multi segment rings and building the SGT, locking concerns, and ep cleanup operations. - Removed some fixme tags for conditions that may not be needed/addressed. - Repurposed the new endpoint stop sync API to be utilized in other places. - Fixed potential compile issue if XHCI sideband config is not defined. ASoC: - Added sound jack control into the Q6USB driver. Allows for userpsace to know when an offload capable device is connected. USB SND: - Avoided exporting _snd_pcm_hw_param_set based on Takashi's recommendation. - Split USB QMI packet header definitions into a separate commit. This is used to properly allow the QMI interface driver to parse and route QMI packets accordingly - Added a "depends on" entry when enabling QC audio offload to avoid compile time issues. Changes in v3: - Changed prefix from RFC to PATCH - Rebased entire series to usb-next - Updated copyright years XHCI: - Rebased changes on top of XHCI changes merged into usb-next, and only added changes that were still under discussion. - Added change to read in the "num-hc-interrupters" device property. ASoC: - qusb6 USB backend - Incorporated suggestions to fetch iommu information with existing APIs - Added two new sound kcontrols to fetch offload status and offload device selection. - offload status - will return the card and pcm device in use tinymix -D 0 get 1 --> 1, 0 (offload in progress on card#1 pcm#0) - device selection - set the card and pcm device to enable offload on. Ex.: tinymix -D 0 set 1 2 0 --> sets offload on card#2 pcm#0 (this should be the USB card) USB SND: - Fixed up some locking related concerns for registering platform ops. - Moved callbacks under the register_mutex, so that - Modified APIs to properly pass more information about the USB SND device, so that the Q6USB backend can build a device list/map, in order to monitor offload status and device selection. Changes in v2: XHCI: - Replaced XHCI and HCD changes with Mathias' XHCI interrupter changes in his tree: https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/?h=feat… Adjustments made to Mathias' changes: - Created xhci-intr.h to export/expose interrupter APIs versus exposing xhci.h. Moved dependent structures to this file as well. (so clients can parse out information from "struct xhci_interrupter") - Added some basic locking when requesting interrupters. - Fixed up some sanity checks. - Removed clearing of the ERSTBA during freeing of the interrupter. (pending issue where SMMU fault occurs if DMA addr returned is 64b - TODO) - Clean up pending events in the XHCI secondary interrupter. While testing USB bus suspend, it was seen that on bus resume, the xHCI HC would run into a command timeout. - Added offloading APIs to xHCI to fetch transfer and event ring information. ASoC: - Modified soc-usb to allow for multiple USB port additions. For this to work, the USB offload driver has to have a reference to the USB backend by adding a "usb-soc-be" DT entry to the device saved into XHCI sysdev. - Created separate dt-bindings for defining USB_RX port. - Increased APR timeout to accommodate the situation where the AFE port start command could be delayed due to having to issue a USB bus resume while handling the QMI stream start command. USB SND: - Added a platform ops during usb_audio_suspend(). This allows for the USB offload driver to halt the audio stream when system enters PM suspend. This ensures the audio DSP is not issuing transfers on the USB bus. - Do not override platform ops if they are already populated. - Introduce a shared status variable between the USB offload and USB SND layers, to ensure that only one path is active at a time. If the USB bus is occupied, then userspace is notified that the path is busy.

[PATCH v1 1/1] treewide: Align match_string() with sysfs_match_string()
by Andy Shevchenko 10 Jun '24

10 Jun '24

Make two APIs look similar. Hence convert match_string() to be a 2-argument macro. In order to avoid unneeded churn, convert all users as well. There is no functional change intended. Signed-off-by: Andy Shevchenko <andriy.shevchenko(a)linux.intel.com> --- Compile tested with `make allyesconfig` and `make allmodconfig` on x86_64, arm, aarch64, powerpc64 (8 builds total). I guess the best is to apply it to Linus' tree directly. And now it seems a good timing as there are no new users of this API either in v6.10-rcX, or in Linux Next. But if you think differently, tell me. arch/powerpc/xmon/xmon.c | 5 ++-- arch/x86/kernel/cpu/mtrr/if.c | 4 +-- crypto/asymmetric_keys/pkcs7_verify.c | 4 +-- drivers/acpi/scan.c | 4 +-- drivers/ata/pata_hpt366.c | 2 +- drivers/ata/pata_hpt37x.c | 2 +- drivers/base/property.c | 6 ++-- drivers/char/ipmi/ipmi_msghandler.c | 2 +- drivers/char/ipmi/ipmi_si_hardcode.c | 2 +- drivers/clk/bcm/clk-bcm2835.c | 4 +-- drivers/clk/rockchip/clk.c | 4 +-- drivers/clk/tegra/clk-tegra124-emc.c | 7 ++--- drivers/cpufreq/amd-pstate.c | 4 +-- drivers/cpufreq/intel_pstate.c | 2 +- .../intel/qat/qat_common/adf_cfg_services.c | 5 ++-- .../gpu/drm/drm_panel_orientation_quirks.c | 2 +- drivers/gpu/drm/i915/display/intel_pipe_crc.c | 2 +- drivers/gpu/drm/nouveau/dispnv04/tvnv17.c | 4 +-- drivers/gpu/drm/nouveau/dispnv50/crc.c | 2 +- drivers/hwmon/ltc4282.c | 14 ++++----- drivers/hwmon/nct6775-platform.c | 6 ++-- drivers/hwtracing/intel_th/msu.c | 2 +- drivers/i2c/busses/i2c-i801.c | 4 +-- drivers/leds/leds-sun50i-a100.c | 2 +- drivers/mfd/omap-usb-host.c | 2 +- drivers/mmc/host/sdhci-xenon-phy.c | 13 ++++----- drivers/mtd/nand/raw/nand_macronix.c | 10 ++----- .../net/ethernet/chelsio/cxgb4/cudbg_lib.c | 6 ++-- .../net/wireless/intel/iwlwifi/mvm/debugfs.c | 2 +- drivers/pci/pcie/aer.c | 2 +- drivers/phy/mediatek/phy-mtk-tphy.c | 8 ++--- drivers/phy/tegra/xusb.c | 4 +-- drivers/pinctrl/mvebu/pinctrl-armada-37xx.c | 6 ++-- drivers/pinctrl/pinmux.c | 6 ++-- drivers/platform/x86/hp/hp-wmi.c | 29 +++++++------------ drivers/platform/x86/msi-ec.c | 4 +-- drivers/power/supply/ab8500_btemp.c | 2 +- drivers/power/supply/ab8500_chargalg.c | 2 +- drivers/power/supply/ab8500_charger.c | 2 +- drivers/power/supply/ab8500_fg.c | 2 +- drivers/staging/gdm724x/gdm_tty.c | 5 ++-- .../int340x_thermal/processor_thermal_rfim.c | 4 +-- .../processor_thermal_wt_req.c | 2 +- drivers/usb/common/common.c | 8 ++--- drivers/usb/dwc3/dwc3-rtk.c | 2 +- drivers/usb/typec/class.c | 14 ++++----- drivers/usb/typec/tipd/core.c | 3 +- drivers/video/fbdev/pxafb.c | 4 +-- fs/bcachefs/compress.c | 2 +- fs/bcachefs/opts.c | 4 +-- fs/bcachefs/util.c | 4 +-- fs/ubifs/auth.c | 8 ++--- include/linux/string.h | 12 +++++++- kernel/cgroup/rdma.c | 2 +- kernel/sched/debug.c | 2 +- kernel/trace/trace.c | 4 +-- kernel/trace/trace_osnoise.c | 4 +-- lib/dynamic_debug.c | 5 ++-- lib/string_helpers.c | 6 ++-- mm/mempolicy.c | 4 +-- mm/vmpressure.c | 4 +-- security/apparmor/lsm.c | 9 +++--- security/integrity/ima/ima_main.c | 2 +- security/integrity/ima/ima_policy.c | 2 +- sound/firewire/oxfw/oxfw.c | 2 +- sound/pci/oxygen/oxygen_mixer.c | 2 +- sound/soc/codecs/max98088.c | 2 +- sound/soc/codecs/max98095.c | 2 +- sound/soc/soc-dapm.c | 5 ++-- 69 files changed, 150 insertions(+), 174 deletions(-) diff --git a/arch/powerpc/xmon/xmon.c b/arch/powerpc/xmon/xmon.c index bd4813bad317..f479cc62674a 100644 --- a/arch/powerpc/xmon/xmon.c +++ b/arch/powerpc/xmon/xmon.c @@ -3478,8 +3478,7 @@ skipbl(void) return c;

[PATCH v2 0/2] tlv320adc3xxx: Allow MICBIAS pins to be used as GPOs
by Ricard Wanderlof 07 Jun '24

07 Jun '24

In some cases, depending on system design, the MICBIAS pins on the chip are not needed as such, but a couple of extra GPIO pins would be useful. This patch allows the MICBIAS pins to be configured in the device tree as general purpose output pins, controlled via the GPIO framework. Owing to their originally intended purpose there are some limitations: when the MICBIAS pins are deactivated, they will float, so will likely need a pulldown in many applications. When activated, they will assume the voltage specified by the micbias1-vg and micbias2-vg properties, respectively, meaning that the resulting output voltage will be 2.0 V, 2.5 V or AVDD . Signed-off-by: Ricard Wanderlof <ricard.wanderlof(a)axis.com> --- Changes in v2: - Corrected typo in yaml document for ti,micbias2-vg property reference - Added dependecies to yaml document for ti,micbias1-gio and ti,micbias2-gpo - Link to v1: https://lore.kernel.org/r/20240529-tlv320adc3xxx-micbias-gpo-v1-0-300d39cec… --- Ricard Wanderlof (2): ASoC: dt-bindings: tlv320adc3xxx: Add MICBIAS-as-GPO properties tlv320adc3xxx: Add support for using MICBIAS pins as GPO .../bindings/sound/ti,tlv320adc3xxx.yaml | 24 +++++ sound/soc/codecs/tlv320adc3xxx.c | 105 ++++++++++++++++----- 2 files changed, 108 insertions(+), 21 deletions(-) --- base-commit: 47d09270d7776e46858a161f94b735640b2fb056 change-id: 20240528-tlv320adc3xxx-micbias-gpo-b8b4d1c846d3 Best regards, -- -- Ricard Wolf Wanderlof ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30

[PATCHv4 9/9] ASoC: dt-bindings: fsl-asoc-card: add compatible for generic codec
by Elinor Montmasson 06 Jun '24

06 Jun '24

Add documentation about new dts bindings following new support for compatible "fsl,imx-audio-generic". Some CPU DAI don't require a real audio codec. The new compatible "fsl,imx-audio-generic" allows using the driver with codec drivers SPDIF DIT and SPDIF DIR as dummy codecs. It also allows using not pre-configured audio codecs which don't require specific control through a codec driver. The new dts properties give the possibility to set some parameters about the CPU DAI usually set through the codec configuration.
