[PATCH] ASoC: ak4613: cares Simple-Audio-Card case for TDM
by Kuninori Morimoto 30 Jun '22

30 Jun '22

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Renesas is the only user of ak4613 on upstream for now, and commit f28dbaa958fbd8 ("ASoC: ak4613: add TDM256 support") added TDM256 support. Renesas tested part of it, because of board connection. It was assuming ak4613 is probed via Audio-Graph-Card, but it might be probed via Simple-Audio-Card either. It will indicates WARNING in such case. This patch fixup it.

[PATCH 1/2] ASoC: codecs: wsa881x: handle timeouts in resume path
by Srinivas Kandagatla 30 Jun '22

30 Jun '22

Currently we do not check if SoundWire slave initialization timeout expired before continuing to access its registers. Its possible that the registers are not accessible if timeout is expired. Handle this by returning timeout in resume path.

[PATCH] ASoC: wm_adsp: Minor clean and redundant code removal
by Charles Keepax 30 Jun '22

30 Jun '22

The cs_dsp core will return an error if passed a NULL cs_dsp struct so there is no need for the wm_adsp_write|read_ctl functions to manually check that. The cs_dsp core will also check the data is within bounds of the control so the additional bounds check is redundant too. Simplify things a bit by removing said code.

Hi Mark Current ASoC has fixup both snd_soc_of_get_dai_link_cpus/codecs(). I guess cpu was copied from codec, but it is using "codec" naming everwhere in "cpu" function. It is strange, and thus, error case will be issue (It should call cpu function instead of codec). This patch tidyup it, and try to cleanup. [1/2] is for bug-fix, [2/2] is for new feature. It needs Tested-by/Reviewed-by/Acked-by from someone.
