[PATCH] ASoC: hdac_hdmi: remove cancel_work_sync in runtime suspend
by Brent Lu 02 Oct '20

02 Oct '20

A deadlock is identified when there are three contexts running at the same time: - a HDMI jack work which is calling snd_soc_dapm_sync(). - user space is calling snd_pcm_release() to close pcm device. - pm is calling runtime suspend function of HDMI codec driver. By removing the clear_dapm_works() invocation in the hdac_hdmi_runtime_suspend() function, the snd_pcm_release() could always returns from dapm_power_widgets() function call without blocking the hdac_hdmi_jack_dapm_work() work thread or being blocked by the hdac_hdmi_runtime_suspend() function. The purpose of the jack work is to enable/disable the dapm jack pin so it's not necessary to cancel the work in runtime suspend function which is usually called when pcm device is closed.

[PATCH V2] ASoC: Intel: boards: Use FS as nau8825 sysclk in nau88125_* machine
by Radoslaw Biernacki 08 Sep '20

08 Sep '20

This single fix address two issues on machines with nau88125: 1) Audio distortion, due to lack of required clock rate on MCLK line 2) Loud audible "pops" on headphones if there is no sysclk during nau8825 playback power up sequence Explanation for: 1) Due to Skylake HW limitation, MCLK pin can only output 24MHz clk rate (it can be only connected to XTAL parent clk). The BCLK pin can be driven by dividers and therefore FW is able to set it to rate required by chosen audio format. According to nau8825 datasheet, 256*FS sysclk gives the best audio quality and the only way to achieve this (taking into account the above limitations) its to regenerate the MCLK from BCLK on nau8825 side by FFL. Without required clk rate, audio is distorted by added harmonics. 2) Currently Skylake does not output MCLK/FS when the back-end DAI op hw_param is called, so we cannot switch to MCLK/FS in hw_param. This patch reduces pop by letting nau8825 keep using its internal VCO clock during widget power up sequence, until SNDRV_PCM_TRIGGER_START when MCLK/FS is available. Once device resumes, the system will only enable power sequence for playback without doing hardware parameter, audio format, and PLL configure. In the mean time, the jack detecion sequence has changed PLL parameters and switched to internal clock. Thus, the playback signal distorted without correct PLL parameters. That is why we need to configure the PLL again in SNDRV_PCM_TRIGGER_RESUME case.

[PATCH 00/16] Add Allwinner H3/H5/H6/A64 HDMI audio
by Clément Péron 04 Sep '20

04 Sep '20

Hi, This a merge of serie: - Add Add H6 I2S support https://patchwork.kernel.org/cover/11497007/ - Add Allwinner H3/H5/A64 HDMI audio https://patchwork.kernel.org/cover/11510511/ I merge both serie because there is a similar issue regarding the I2S polarity. This need to be investigated under a scope and see if the comment is still true for Allwinner H6 and previous SoC. LibreElec team found that we have to introduce the "simple-audio-card,frame-inversion" property with recent mainline change. In order to make HDMI audio work. Maybe the I2S polarity is good or maybe the silicium has an issue but not present for HDMI I2S or not present in TDM mode... I cannot do it myself, so if someone want to to do it please feel free. Regarding the discussion we had here: https://patchwork.kernel.org/patch/11510521/ I didn't switch to generic hdmi card-name and used name like: sun8i-h3-hdmi, sun50i-h6-hdmi, etc.... Despite this wrong comment the rest of the serie introduce some fix that should be merged even if it's without the H6 support.

[PATCH 0/7] Allwinner A64 digital audio codec fixes
by Samuel Holland 28 Aug '20

28 Aug '20

This series fixes a couple of issues with the digital audio codec in the Allwinner A64 SoC: 1) Left/right channels were swapped when playing/recording audio 2) DAPM topology was wrong, breaking some kcontrols This is the minimum set of changes necessary to fix these issues in a backward-compatible way. For that reason, some DAPM widgets still have incorrect or confusing names; those and other issues will be fixed in later patch sets.

[PATCH] ASoC: intel/skl/hda - fix probe regression on systems without i915
by Kai Vehmanen 27 Aug '20

27 Aug '20

Starting in commit cbc7a6b5a87a ("ASoC: soc-card: add snd_soc_card_add_dai_link()"), error value from ASoc add_dai_link() is no longer ignored. The generic HDA machine driver relied on the old semantics to disable i915 HDMI/DP audio codec at runtime. If no display codec was present, add_dai_link() returned an error, but this was ignored and rest of the card was successfully probed. Fix the problem by changing the machine driver add_dai_link() to not return an error in this case.

[PATCH] ASoC: meson: cards: deal dpcm flag change
by Jerome Brunet 27 Aug '20

27 Aug '20

Commit b73287f0b074 ("ASoC: soc-pcm: dpcm: fix playback/capture checks") changed the meaning of dpcm_playback/dpcm_capture and now requires the CPU DAI BE to aligned with those flags. This broke all Amlogic cards with uni-directional backends (All gx and most axg cards). While I'm still confused as to how this change is an improvement, those cards can't remain broken forever. Hopefully, next time an API change is done like that, all the users will be updated as part of the change, and not left to fend for themselves. Fixes: b73287f0b074 ("ASoC: soc-pcm: dpcm: fix playback/capture checks") Signed-off-by: Jerome Brunet <jbrunet(a)baylibre.com> --- Hi, For the cards be actually fixed, change 'ASoC: core: use less strict tests for dailink capabilities' will need to merged as well. snd_soc_dai_link_set_capabilities() as implemented in 25612477d20b5 ('ASoC: soc-dai: set dai_link dpcm_ flags with a helper') does not support link with multiple codec with different direction capabilities.
