[PATCH v1] ASoc: tas2781: Support still work when only RCA binary loading well without dsp firmware loading.
by Shenghao Ding 23 May '24

23 May '24

In only RCA binary loading case, only default dsp program will be work inside the chip. Signed-off-by: Shenghao Ding <shenghao-ding(a)ti.com> --- v1: - Split out the different logical changes into different patches. - rename tasdevice_dsp_fw_state -> tasdevice_fw_state, the fw are not only dsp fw, but also RCA(Reconfigurable data, such as acoustic data and register setting, etc). - Add TASDEVICE_RCA_FW_OK in tasdevice_fw_state to identify the state that only RCA binary file has been download successfully, but dsp fw is not loaded or loading failure. - Add the this strategy into tasdevice_tuning_switch. - If one side of the if/else has a braces both should in tasdevice_tuning_switch. - Identify whehter both RCA and DSP have been loaded or only RCA has been loaded in tasdevice_fw_ready. - Add check fw load status in tasdevice_startup. - remove ret in tasdevice_startup to make th code neater. --- include/sound/tas2781-dsp.h | 3 ++- sound/soc/codecs/tas2781-fmwlib.c | 14 ++++++++++---- sound/soc/codecs/tas2781-i2c.c | 30 ++++++++++++++++++------------ 3 files changed, 30 insertions(+), 17 deletions(-) diff --git a/include/sound/tas2781-dsp.h b/include/sound/tas2781-dsp.h index 7fba7ea26a4b..92d68ca5eafb 100644 --- a/include/sound/tas2781-dsp.h +++ b/include/sound/tas2781-dsp.h @@ -117,10 +117,11 @@ struct tasdevice_fw { struct device *dev; }; -enum tasdevice_dsp_fw_state { +enum tasdevice_fw_state { TASDEVICE_DSP_FW_NONE = 0, TASDEVICE_DSP_FW_PENDING, TASDEVICE_DSP_FW_FAIL, + TASDEVICE_RCA_FW_OK, TASDEVICE_DSP_FW_ALL_OK, }; diff --git a/sound/soc/codecs/tas2781-fmwlib.c b/sound/soc/codecs/tas2781-fmwlib.c index 265a8ca25cbb..cfa022ef4a59 100644 --- a/sound/soc/codecs/tas2781-fmwlib.c +++ b/sound/soc/codecs/tas2781-fmwlib.c @@ -2324,13 +2324,18 @@ void tasdevice_tuning_switch(void *context, int state) struct tasdevice_fw *tas_fmw = tas_priv->fmw; int profile_cfg_id = tas_priv->rcabin.profile_cfg_id; - if (tas_priv->fw_state == TASDEVICE_DSP_FW_FAIL) { - dev_err(tas_priv->dev, "DSP bin file not loaded\n"); + /* + * Only RCA file loaded can still work with default dsp program inside + * the chip?

[PATCH v2 0/2] Add PDM controller for StarFive JH8100 SoC
by Xingyu Wu 23 May '24

23 May '24

The Pulse Density Modulation (PDM) controller is a digital PDM microphone interface controller and decoder that supports both mono/stereo PDM format, and a Inter-IC Sound (I2S) transmitter that outputs standard stereo audio data to another device. The PDM controller includes two PDM blocks, each PDM block can drive one bitstream sampling clock and two bitstream coming data (mono/stereo) with sampling clock rising and falling edge. The first patch adds documentation to describe PDM controller bindings. And the second patch adds PDM driver for the StarFive JH8100 SoC. The DTS patch of PDM controller will be submitted after the patchs of JH8100 DTS are accepted. Changes since v1: - Changed the subject prefix of the bindings. - Dropped the confused property in the bindings. - Added the $ref to dai-common. - Changed the kcontrol names and put it into ops. - Added the reset when device resume. - Modified two blocks into a whole PDM which supports up to 4 channels of recorder. v1: https://lore.kernel.org/all/20240307033708.139535-1-xingyu.wu@starfivetech.… Xingyu Wu (2): ASoC: dt-bindings: Add PDM controller for the StarFive JH8100 SoC ASoC: starfive: Add PDM controller support .../bindings/sound/starfive,jh8100-pdm.yaml | 82 ++++ MAINTAINERS | 7 + sound/soc/starfive/Kconfig | 7 + sound/soc/starfive/Makefile | 1 + sound/soc/starfive/jh8100_pdm.c | 447 ++++++++++++++++++ 5 files changed, 544 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/starfive,jh8100-pdm.yaml create mode 100644 sound/soc/starfive/jh8100_pdm.c -- 2.25.1

topology: pre-processor: Introduce extends/overrides keywords for classes
by GitHub pull_request - edited 23 May '24

23 May '24

alsa-project/alsa-utils pull request #268 was edited from ranj063: Introduce a new keyword "Subtreecopy" for extending existing conf nodes with additional nodes. This feature is useful for extending previous pipeline class definitions with the addition of one or more widgets without having to duplicate everything in the new class definition. For example: Consider a pipeline class definition as below. Note that only the widgets & routes are shown here. ``` Class.Pipeline.mixout-gain-dai-copier-playback { Object.Widget { mixout."1" {} dai-copier."1" {} gain."1" {} pipeline."1" {} } Object.Base { !route [ { source mixout.$index.1 sink gain.$index.1 } ] } } ``` If we want to extend this pipeline with the addition of an eqiir/eqfir, we can create a Subtreecopy node with type extend as follows: ``` Subtreecopy.mixout-gain-eqiir-eqfir-dai-copier-playback { source "Class.Pipeline.mixout-gain-dai-copier-playback" target "Class.Pipeline" type extend Object.Widget { eqiir.1 {} eqfir.1 {} } Object.Base { !route [ { source gain.$index.1 sink eqiir.$index.1 } { source eqiir.$index.1 sink eqfir.$index.1 } ] } } ``` But if we want to modify an existing pipeline class while modifying the order of widgets and/or inserting new widgets, we should use the type "override" instead. This allows for adding new widgets to the list of widgets in the base class definition while also allowing overriding the routes to allow inserting the new widgets and reordering the widgets in the base class. For example, if we want to add a drc widget between the gain and the eqiir modules in the above class, we can do the following: ``` Subtreecopy.mixout-efx-dai-copier-playback { source "Class.Pipeline.mixout-gain-eqiir-eqfir-dai-copier-playback" target "Class.Pipeline" type override Object.Widget { drc.1 {} } Object.Base { !route [ { source mixout.$index.1 sink gain.$index.1 } { source gain.$index.1 sink drc.$index.1 } { source drc.$index.1 sink eqiir.$index.1 } { source eqiir.$index.1 sink eqfir.$index.1 } ] } } ``` Note that the routes array contains all the routes in the new subtreecopy definition. This subtreecopy feature can also be used to copy normal config blocks without having the need to duplicate information. For example, if all the widgets in a pipeline support the same audio formats, we can define it as follows: ``` Class.Pipeline.dai-copier-eqiir-module-copier-capture { formats { num_input_audio_formats 2 num_output_audio_formats 2 Object.Base.input_audio_format [ { in_bit_depth 32 in_valid_bit_depth 32 } { in_channels 4 in_bit_depth 32 in_valid_bit_depth 32 in_ch_cfg $CHANNEL_CONFIG_3_POINT_1 in_ch_map $CHANNEL_MAP_3_POINT_1 } ] Object.Base.output_audio_format [ { out_bit_depth 32 out_valid_bit_depth 32 } { out_channels 4 out_bit_depth 32 out_valid_bit_depth 32 out_ch_cfg $CHANNEL_CONFIG_3_POINT_1 out_ch_map $CHANNEL_MAP_3_POINT_1 } ] } Object.Widget { dai-copier."1" { type dai_out num_output_pins 1 Subtreecopy.formats { source "Class.Pipeline.dai-copier-eqiir-module-copier-capture.formats" type override } } eqiir."1" { Subtreecopy.formats { source "Class.Pipeline.dai-copier-eqiir-module-copier-capture.formats" type override } Object.Control.bytes."1" { IncludeByKey.DMIC0_DAI_EQIIR { "passthrough" "include/components/eqiir/passthrough.conf" "highpass_40hz_0db" "include/components/eqiir/highpass_40hz_0db_48khz.conf" "highpass_40hz_20db" "include/components/eqiir/highpass_40hz_20db_48khz.conf" } } } module-copier."2" { Subtreecopy.formats { source "Class.Pipeline.dai-copier-eqiir-module-copier-capture.formats" type override } } pipeline."1" { priority 0 lp_mode 0 } } } ``` The subtreecopy node in each widget ensures that the pipeline formats are applied to all widgets without the need for duplicating them for each widget.

[PATCH v3 0/8] ASoC: samsung: midas-audio: Add GPIO-based headset jack detection
by Artur Weber 22 May '24

22 May '24

Many of Samsung's Exynos 4 devices share the same midas-audio driver to handle the codec setup. While most of these devices, including the Midas itself, use the jack detection provided by the WM8994 driver, other devices such as the Samsung Galaxy Tab 3 8.0 (lt01) use two GPIOs and an ADC channel to determine jack insertion, the jack's type, and button presses (for headsets with volume up/down/play buttons). In the downstream kernel, this behavior is implemented in the sec-jack driver[1], and the per-device settings are configured in *-jack.c files in the mach folder (see e.g. the Tab 3's implementation[2]). This patchset implements this mechanism in the midas_wm1811.c driver, and adds new DTS options to allow for its configuration. It also enables jack detection for the Samsung Galaxy Tab 3 8.0. A very similar mechanism was already present in the aries_wm8994.c driver[3]; this implementation heavily borrows from it, though there are a few extra cleanups as well.

[PATCH v4 0/7] ASoC: codecs: wcd937x: add wcd937x audio codec support
by Mohammad Rafi Shaik 22 May '24

22 May '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 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 | 95 + .../bindings/sound/qcom,wcd937x.yaml | 80 + sound/soc/codecs/Kconfig | 20 + sound/soc/codecs/Makefile | 7 + sound/soc/codecs/wcd937x-sdw.c | 1174 +++++++ sound/soc/codecs/wcd937x.c | 3040 +++++++++++++++++ sound/soc/codecs/wcd937x.h | 653 ++++ 7 files changed, 5069 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: 75fa778d74b786a1608d55d655d42b480a6fa8bd -- 2.25.1

[PATCH v3 0/2] Add Cadence I2S-MC controller driver
by Xingyu Wu 22 May '24

22 May '24

The Cadence Multi-channel I2S (I2S-MC) Controller implements a function of the multi-channel (up to 8-channel) bus. Each stereo channel combines functions of a transmitter and a receiver, and can switch freely between them. Each channel has independent gating, clock and interruption control. It also support some of these channels are used as playback and others can also be used as record in the same time. Four I2S controllers are used on the StarFive JH8100 SoC. Two of the I2S controllers use two stereo channels, one of them use four channels, and one use eight. It had tested on the fpga with WM8960 and PDM. Changes since v2: - Dropped the description of interrupts in bindings. - Modified the properties like 'compatible' and 'required'. - Defined the special property in top-level and made it false in other case in the bindings. - Added the test of other format in the driver. - Changed the return values and switch the TX and RX channels for convenience. - Modified the macros about 'SND_SOC_DAIFMT_CBM_CFM'. - Added pm_runtime_set_active() to fix the state of pm_runtime. v2: https://lore.kernel.org/all/20240320090239.168743-1-xingyu.wu@starfivetech.… Changes since v1: - Added new compatible for StarFive JH8100 SoC and a special property to be got as the max channels number in the bindings. - Dropped the useless '|' in the bindings. - Moved the drivers to a new folder named 'cdns' and modified the name of functions. v1: https://lore.kernel.org/all/20231221033223.73201-1-xingyu.wu@starfivetech.c… Xingyu Wu (2): ASoC: dt-bindings: Add bindings for Cadence I2S-MC controller ASoC: cdns: Add drivers of Cadence Multi-Channel I2S Controller .../bindings/sound/cdns,i2s-mc.yaml | 109 +++ MAINTAINERS | 6 + sound/soc/Kconfig | 1 + sound/soc/Makefile | 1 + sound/soc/cdns/Kconfig | 18 + sound/soc/cdns/Makefile | 3 + sound/soc/cdns/cdns-i2s-mc-pcm.c | 285 +++++++ sound/soc/cdns/cdns-i2s-mc.c | 704 ++++++++++++++++++ sound/soc/cdns/cdns-i2s-mc.h | 151 ++++ 9 files changed, 1278 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/cdns,i2s-mc.yaml create mode 100644 sound/soc/cdns/Kconfig create mode 100644 sound/soc/cdns/Makefile create mode 100644 sound/soc/cdns/cdns-i2s-mc-pcm.c create mode 100644 sound/soc/cdns/cdns-i2s-mc.c create mode 100644 sound/soc/cdns/cdns-i2s-mc.h -- 2.25.1
