[alsa-devel] [PATCH] ASoC: stm32: spdifrx: retry synchronization in sync state
by Olivier Moysan 14 Oct '19

14 Oct '19

When STM32 SPDIFRX is in sync state, allow multiple synchro attempts, instead of exiting on first unsuccessful trial. This is useful when spdif signal is not immediately available on input. This also allows Pulseaudio to check iec capture device availability when no signal is present.

[alsa-devel] [PATCH v2 00/10] ASoC: mediatek: mt8183-mt6358-ts3a227-max98357: support WoV
by Tzung-Bi Shih 14 Oct '19

14 Oct '19

This series makes mt6358, cros_ec_codec, and mt8183-mt6358-ts3a227-max98357 support WoV (wake on voice). The first 3 commits are some cleanups and refactors. It looks like breaking the existing interface. But please be noticed that, the cros_ec_codec has not used by any real device yet. The refactor is very necessary to keep the style consistent and for easier to further extend and maintain. platform/chrome: cros_ec: remove unused EC feature ASoC: cros_ec_codec: refactor I2S RX ASoC: cros_ec_codec: extract DMIC EC command from I2S RX The 4th commit extends the feature offered from EC codec. platform/chrome: cros_ec: add common commands for EC codec The 5th commit changes the behavior of setting and getting DMIC gains. ASoC: cros_ec_codec: read max DMIC gain from EC codec The 6th and 7th commit make cros_ec_codec support WoV. ASoC: dt-bindings: cros_ec_codec: add SHM bindings ASoC: cros_ec_codec: support WoV The 8th commit sets necessary registers on mt6358 to support WoV. ASoC: mediatek: mt6358: support WoV The last 2 commit make machine driver mt8183-mt6358-ts3a227-max98357 support WoV if ec-codec is in DTS.

This patch adds support for the 8 channel PDM-to-I2S/TDM converter. The ADAU7118 converts four stereo pulse density modulation (PDM) bitstreams into one pulse code modulation (PCM) output stream. The source for the PDM data can be eight microphones or other PDM sources. The PCM audio data is output on a serial audio interface port in either inter-IC serial (I2S) or time domain multiplexed (TDM) format. Signed-off-by: Nuno Sá <nuno.sa(a)analog.com> --- Changes in v2: * Use C++ coment style on the entire comment in the .c files; * Do not use ternery operator; * Do not use `devm_regulator_get_optional` as the device always requires power; * Let DAPM suspend/resume the device. Changes in v3: * no changes.

[alsa-devel] [PATCH 00/21] ASoC: soc-core cleanup - step 4
by Kuninori Morimoto 11 Oct '19

11 Oct '19

Hi Mark Cc Pierre-Louis These are step4 of soc-core cleanup. These related to soc-topology. If my understanding and my code are correct, there is no effect to topology side, but I can't test. I'm not sure who can test these, but I guess Pierre-Louis knows ? Pierre-Louis, can you help it ?
