[PATCH AUTOSEL 5.10 084/114] ASoC: ops: Enforce platform maximum on initial value

[Sasha Levin]

From: Martin Povišer <povik+lin@cutebit.org>

[ Upstream commit 783db6851c1821d8b983ffb12b99c279ff64f2ee ]

Lower the volume if it is violating the platform maximum at its initial
value (i.e. at the time of the 'snd_soc_limit_volume' call).

[PATCH AUTOSEL 5.10 085/114] ASoC: tas2764: Power up/down amp on mute ops

[Sasha Levin]

From: Hector Martin <marcan@marcan.st>

[ Upstream commit 1c3b5f37409682184669457a5bdf761268eafbe5 ]

The ASoC convention is that clocks are removed after codec mute, and
power up/down is more about top level power management. For these chips,
the "mute" state still expects a TDM clock, and yanking the clock in
this state will trigger clock errors. So, do the full
shutdown<->mute<->active transition on the mute operation, so the amp is
in software shutdown by the time the clocks are removed.

This fixes TDM clock errors when streams are stopped.

[PATCH AUTOSEL 5.10 086/114] ASoC: soc-dai: check return value at snd_soc_dai_set_tdm_slot()

[Sasha Levin]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

[ Upstream commit 7f1186a8d738661b941b298fd6d1d5725ed71428 ]

snd_soc_dai_set_tdm_slot() calls .xlate_tdm_slot_mask() or
snd_soc_xlate_tdm_slot_mask(), but didn't check its return value.
Let's check it.

This patch might break existing driver. In such case, let's makes
each func to void instead of int.
