[PATCH v1 0/3] ASoC: meson: Fix mixer-test issues
by Mark Brown 21 Apr '22

21 Apr '22

These patches fix event generation issues in the custom controls in the Meson drivers detected by mixer-test and by inspection once I saw the pattern in these drivers. I'm also seeing other failures due to these controls having invalid values, eg: # # AIU ACODEC SRC.0 value 3 more than item count 3 but without documentation I'm not sure how to interpret/fix these - either the value should be fixed up on startup or there should be an extra value there (disconnected possibly?).

[PATCH] ASoC: audio-graph-card2: indicate "Experimental stage" warning only when successed
by Kuninori Morimoto 21 Apr '22

by Kuninori Morimoto 21 Apr '22

21 Apr '22

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Renesas Sound is very complex, and thus it needs to use rsnd_node_fixed_index() to know enabled pin index.

[PATCH v4] ASoC: codecs: wsa881x: add runtime pm support
by Srinivas Kandagatla 21 Apr '22

21 Apr '22

WSA SoundWire Controller does not support Clock stop and performs a soft reset on suspend resume path. Its recommended that WSA881x codecs connected to this are also reset using a hard reset during suspend resume. So this codec driver performs a hard reset during suspend resume cycle.
