Merge series "ASoC: soc-pcm: cleanup each functions" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>: Hi Mark These are v2 of soc-pcm cleanup patches. These has no relationship to each other. My 1 concern is [3/8] patch. I think it is no problem, but I'm not 100% sure why current code was such code. Pierre-Louis / Liam might about something. v1 -> v2 - soc_cpu/codec_dai_name() is now inline function - rename soc_pcm_care_symmetry() to soc_pcm_update_symmetry() v2 -> v3 - log fix at [6/8] - Thus, it will be minus users at (2). + Thus, users will be a negative number at (2) Link: https://lore.kernel.org/r/87tupuqqc8.wl-kuninori.morimoto.gx@renesas.com Link: https://lore.kernel.org/r/87tupqpg9x.wl-kuninori.morimoto.gx@renesas.com Kuninori Morimoto (8): ASoC: soc-pcm: check DAI activity under soc_pcm_apply_symmetry() ASoC: soc-pcm: add soc_cpu/codec_dai_name() macro ASoC: soc-pcm: direct copy at snd_soc_set_runtime_hwparams() ASoC: soc-pcm: add soc_pcm_update_symmetry() ASoC: soc-pcm: add soc_hw_sanity_check() ASoC: soc-pcm: fixup dpcm_be_dai_startup() user count ASoC: soc-pcm: remove unneeded !rtd->dai_link check ASoC: soc-pcm: share DPCM BE DAI stop operation include/sound/soc-dpcm.h | 8 +- sound/soc/soc-compress.c | 2 +- sound/soc/soc-pcm.c | 243 ++++++++++++++++----------------------- 3 files changed, 105 insertions(+), 148 deletions(-) -- 2.25.1

soc-pcm has very similar but different DPCM BE DAI stop operation at 1) dpcm_be_dai_startup() error case rollback 2) dpcm_be_dai_startup_unwind() 3) dpcm_be_dai_shutdown() The differences are 1) for rollback 2) Doesn't check by snd_soc_dpcm_be_can_update() (Is this bug ?) 3) Do soc_pcm_hw_free() if it was not !OPENed and !HW_FREEed, and call soc_pcm_close(). We can share same code by 1) hw_free is not needed. Needs last dpcm as rollback. 2) hw_free is not needed. 3) hw_free is needed. This patch adds new dpcm_be_dai_stop() and share these 3.

Current soc_pcm_open() is checking runtime->hw parameters, but having such function is very helpful for reading code. This patch adds new soc_hw_sanity_check() and checks runtime->hw parameters there. And print its debug message there, too. Debug message print out timing is exchanged after this patch, but it is not a big deal, because it is for debug. Signed-off-by:

When DMI information is not present, trying to assign the card long name results in the following warning. WARNING KERN tegra-audio-graph-card sound: ASoC: no DMI vendor name! The initial solution suggested was to test if the card device is an ACPI one. This causes a regression visible to userspace on all Intel platforms, with UCM unable to load card profiles based on DMI information: the card devices are not necessarily ACPI ones, e.g. when the parent creates platform devices on Intel devices. To fix this problem, this patch exports the existing dmi_available variable and tests it in the ASoC core.

Merge series "Add I2S-MCC support for Microchip's SAMA7G5" from Codrin Ciubotariu <codrin.ciubotariu@microchip.com>: SAMA7G5 includes an updated version of I2S-MCC, found previously on SAM9X60. This controller includes 8 data pins, 4 for playback and 4 for capture. For I2S and LEFT_J formats, these pins can be used to send/receive up to 8 audio channels. For DSP_A, with TDM, any pins pair (DIN/DOUT) from these 4 can be selected to send/receive data. This version also includes 2 FIFOs (send and receive). This patch set starts by moving the driver's bindings to yaml and continues with adding a new compatible for the SAMA7G5 variant, followed by the changes needed for I2S/LEFT_J support, TDM pin pair selection and FIFO support, exclusively for SAMA7G5. Changes in v2: - moved DT binding conversion patch from the beginning to the end of the patch serieses - patches that update the DT binding are modified to change .txt file instead of .yaml Codrin Ciubotariu (7): dt-bindings: mchp,i2s-mcc: Add SAMA7G5 to binding ASoC: mchp-i2s-mcc: Add compatible for SAMA7G5 ASoC: mchp-i2s-mcc: Add multi-channel support for I2S and LEFT_J formats dt-bindings: mchp,i2s-mcc: Add property to specify pin pair for TDM ASoC: mchp-i2s-mcc: Add support to select TDM pins ASoC: mchp-i2s-mcc: Add FIFOs support ASoC: convert Microchip I2SMCC binding to yaml .../bindings/sound/mchp,i2s-mcc.yaml | 108 ++++++++++++ .../bindings/sound/mchp-i2s-mcc.txt | 43 ----- sound/soc/atmel/Kconfig | 3 + sound/soc/atmel/mchp-i2s-mcc.c | 161 +++++++++++++++--- 4 files changed, 252 insertions(+), 63 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/mchp,i2s-mcc.yaml delete mode 100644 Documentation/devicetree/bindings/sound/mchp-i2s-mcc.txt -- 2.27.0 -

In case of error, the function devm_regmap_init_sdw_mbq() and devm_regmap_init_sdw() returns ERR_PTR() not NULL. The NULL test in the return value check should be replaced with IS_ERR(). Fixes: 393c52d2d109 ("ASoC: rt715-sdca: Add RT715 sdca vendor-specific driver") Reported-by: -

The PLL is only needed for sclk < 11289600 Hz and cs42l42_pll_config() will not configure it for higher rates. So it must only be enabled when it is needed. Signed-off-by:

There must be a delay of at least 150us after writing SCLK_PRESENT before issuing another I2C write. This is done using struct reg_sequence because it can specify a delay after the write and the whole sequence is written atomically. Signed-off-by:
