Writing documentation for simple device tree ASoC cards
by John Watts 27 Mar '24

27 Mar '24

Hello! I've spent way too much time digging through emails, documentation and kernel source code to form a mental model that lets me understand and use simple-sound-card, audio-graph-card and audio-graph-card2. There's really no introductory documentation geared towards people who are writing device trees intending to glue together multiple audio components in to a single sound card. I'm deciding I'll try and take up this task to provide some basic documentation for this. Before starting I would like to quickly go over some notes in case I'm actually just incredibly wrong. I'd rather find that out now than later. As a general ASoC refresher: - ALSA provides PCM interfaces and controls to a sound card - ASoC introduces the concept of components - Components are what you instantiate with the device tree - Components can be asked to set a clock or create a PCM stream - Components have one or more DAIs - DAIs represent capabilities of a stream - Components have DAPM widgets for power management - These can be related to physical pins on the board or DAI streams - CPU components are ones that ALSA can use directly to process data - Codec components provide information about DAIs or drive streams Most of this is already explained in the documentation. The generic sound cards you can create using simple-sound-card and audio-graph-card are machine drivers. Their jobs are to ensure that when using a DAI all the related components, clocking and power management is set up and ready for use. This is done by: - Linking multiple DAIs together - Connecting DAPM widgets together to power on components - Calculate and setting the shared clock (usually mclk) - Setting DAI properties (like TDM slots and width) - Adding widgets for jack detection DAI linking isn't explained in the documentation but was a core part of my confusion when trying to use these cards: I didn't understand if it represented some relationship between physical pins, PCM channels, etc. My fuzzy model of a DAI link is that it exists to group DAIs (and thus components) necessary to acheive a desired data flow, where that flow is left up to the components themselves to implement. There's a lot of examples for actually using the simple family of cards but I imagine documenting the above would help people troubleshoot or describe their problems better. Other minor notes: - sound-name-prefix is very useful and fits in somewhere here - audio-graph-cards don't support GPIO jacks from what I can see I also have noticed that with audio-graph-card you can't use a DAI multiple times in different cards. This makes sense but is this due to the way graphs and endpoints work or due to the underlying sound system? This problem and jacks seem to point towards maybe allowing specification of DAPM widgets in the device tree, and maybe kcontrols for selecting which codec to use? I'm not sure. It would also be useful to understand the scope of these simple cards. Complex audio needs like mine seem to be outside the scope at the moment and require writing a custom card driver. Perhaps it's worth taking that as an opportunity to write a driver using the simple card framework as an example? John.

[PATCH 0/3] ALSA: hda/tas2781: fixes for 6.9-rc1
by Gergo Koteles 27 Mar '24

27 Mar '24

Hi, This series removes the no longer needed digital gain kcontrol, which caused problems in tas2563, because the register does not exists there. This series also adds locking and debug statements to the other kcontrols. They sometimes ran in parallel with tasdev_fw_ready, and caused weird sound problems. https://github.com/tomsom/yoga-linux/issues/58 Regards, Gergo Gergo Koteles (3): ALSA: hda/tas2781: remove digital gain kcontrol ALSA: hda/tas2781: add locks to kcontrols ALSA: hda/tas2781: add debug statements to kcontrols include/sound/tas2781-tlv.h | 1 - sound/pci/hda/tas2781_hda_i2c.c | 103 +++++++++++++++++++++----------- 2 files changed, 68 insertions(+), 36 deletions(-) base-commit: 4cece764965020c22cff7665b18a012006359095 -- 2.44.0

[PATCH v4 0/7] Add support for the internal RK3308 audio codec
by Luca Ceresoli 26 Mar '24

26 Mar '24

This series adds a driver for the internal audio codec of the Rockchip RK3308 SoC, along with some related patches. This codec is internally connected to the I2S peripherals on the same chip, and it has some peculiarities arising from that interconnection. For proper bidirectional operation with the internal codec at any possible combination of sampling rates, the I2S peripheral needs two clock sources (tx and rx), while connection with an external codec commonly needs only one. Since v5.16 there is a driver for the I2S in sound/soc/rockchip/rockchip_i2s_tdm.c, but in some cases it does not configure correctly the clocks, resulting in an unnecessarily inaccurate rate. Patch 1 fixes this. Patches 2-4 add the codec driver along with the bindings and a new helper macro. Patches 5-7 add to the SoC DT file two I2S controllers (those which are internally connected to the internal codec) and the codec itself and enable the driver in the ARM64 defconfig.

[PATCH v3 00/22] SoC: Cleanup MediaTek soundcard machine drivers
by AngeloGioacchino Del Regno 26 Mar '24

26 Mar '24

Changes in v3: - Added audio-routing names in enum in all yaml files - Added mention of disallowing old and new properties together in commit message of bindings patches - Fixed validation errors with sound-card-common.yaml inclusion due to missing model property in examples - Removed `else` enforcing headset-codec/speaker-codecs requirement if xxx-dai-link not present to avoid future commit noise as the deprecated statement will disallow deprecated properties as required Changes in v2: - Bindings: Changed link-name/codec/clk-provider to remove `items` and leave just the enum - Moved .*-dai-link pattern additionalProperties after `type: object` - Added ref to sound-card-common.yaml - Fixed dai-link-xxx -> xxx-dai-link typo in example comment This series performs a cleanup of most of the MediaTek AFE drivers and soundcard machine drivers, reducing code duplication and setting a base to be consistent with their devicetree bindings, as many of those are using different properties and nodes for no good reason. Summarizing: - Commonizes functions and ops where possible - Adds a common probe mechanism, increasing maintainability of soundcard drivers for older MediaTek SoCs - Migrates all drivers to support the new bindings - Obviously retains compatibility with old device trees - Reduces machine-specific parameters hardcoding in drivers - Can now set machine-specific params in device tree - Uses the `audio-routing` and `dai-link` nodes like some other non-MediaTek SoC sound drivers - Imposes consistency between MediaTek ASoC machine soundcard drivers bindings - Reduces code size and greatly reduces the amount of code that will be required for newer drivers (retaining compatibility with the old bindings was costly in terms of code size, otherwise this series would've removed ~1000 more lines, or something along that line). This series was (manually) tested on MT8173, MT8192, MT8195 and MT8186 Chromebooks.

[PATCH v2 0/5] ASoC: Harden DAPM route checks and Intel fixes
by Cezary Rojewski 26 Mar '24

26 Mar '24

Set of loosely connected patches. Most impactful change is dropping any permisiveness when snd_soc_dapm_add_routes() fails in soc-topology.c To do it safely, disable route checks for all skylake-driver boards. Relevant background: Since commit daa480bde6b3 ("ASoC: soc-core: tidyup for snd_soc_dapm_add_routes()") route checks are no longer permissive. Probe failures for Intel boards have been partially addressed by commit a22ae72b86a4 ("ASoC: soc-core: isable route checks for legacy devices") and its follow up but only skl_nau88l25_ssm4567.c is patched. The rest of the boards still need fixing. After that, removal of copy-pastas found in ssm4567.c and redundant code in i2s_test.c for avs-boards. Changes in v2: - glk_rt5682_max98357a.c and skl_hda_dsp_generic.c now disable route checks only for the skylake-drvier - asoc now logs failures of snd_soc_dapm_add_routes() in soc-topology.c Amadeusz Sławiński (1): ASoC: Intel: avs: i2s_test: Remove redundant dapm routes Cezary Rojewski (4): ASoC: Intel: Disable route checks for Skylake boards ASoC: topology: Do not ignore route checks when parsing graphs ASoC: Intel: avs: ssm4567: Do not ignore route checks ASoC: Intel: avs: ssm4567: Board cleanup sound/soc/intel/avs/boards/i2s_test.c | 79 ------------------- sound/soc/intel/avs/boards/ssm4567.c | 5 +- sound/soc/intel/boards/bxt_da7219_max98357a.c | 1 + sound/soc/intel/boards/bxt_rt298.c | 1 + sound/soc/intel/boards/glk_rt5682_max98357a.c | 2 + sound/soc/intel/boards/kbl_da7219_max98357a.c | 1 + sound/soc/intel/boards/kbl_da7219_max98927.c | 4 + sound/soc/intel/boards/kbl_rt5660.c | 1 + sound/soc/intel/boards/kbl_rt5663_max98927.c | 2 + .../intel/boards/kbl_rt5663_rt5514_max98927.c | 1 + sound/soc/intel/boards/skl_hda_dsp_generic.c | 2 + .../soc/intel/boards/skl_nau88l25_max98357a.c | 1 + sound/soc/intel/boards/skl_rt286.c | 1 + sound/soc/soc-topology.c | 11 ++- 14 files changed, 27 insertions(+), 85 deletions(-) -- 2.25.1

[PATCH v3 0/5] ASoC: fsl: Support register and unregister rpmsg sound card through remoteproc
by Chancel Liu 26 Mar '24

26 Mar '24

echo /lib/firmware/fw.elf > /sys/class/remoteproc/remoteproc0/firmware (A) echo start > /sys/class/remoteproc/remoteproc0/state (B) echo stop > /sys/class/remoteproc/remoteproc0/state The rpmsg sound card is registered in (A) and unregistered in (B). After "start", imx-audio-rpmsg registers devices for ASoC platform driver and machine driver. Then sound card is registered. After "stop", imx-audio-rpmsg unregisters devices for ASoC platform driver and machine driver. Then sound card is unregistered. changes in v2 - Fix build errors reported by kernel test robot changes in v3 - Add a new patch for fsl_rpmsg to register CPU DAI with rpmsg channel name - Update imx-rpmsg.c to get DT node of ASoC CPU DAI device with rpmsg channel name instead of using undocumented bindings Chancel Liu (5): ASoC: fsl: imx-pcm-rpmsg: Register component with rpmsg channel name ASoC: fsl: imx-audio-rpmsg: Register device with rpmsg channel name ASoC: fsl: Let imx-audio-rpmsg register platform device for card ASoC: fsl: fsl_rpmsg: Register CPU DAI with name of rpmsg channel ASoC: fsl: imx-rpmsg: Update to correct DT node sound/soc/fsl/fsl_rpmsg.c | 43 ++++++++++++++++++++------------- sound/soc/fsl/imx-audio-rpmsg.c | 21 +++++++++++++--- sound/soc/fsl/imx-pcm-rpmsg.c | 11 ++++++--- sound/soc/fsl/imx-rpmsg.c | 28 ++++++++++++++------- 4 files changed, 71 insertions(+), 32 deletions(-) -- 2.43.0
