[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
