respective mixer, which can be set from -31 dB to 0 dB in 32 steps.

ASoC: codecs/jz4770: Add DAPM widget to set HP out to cap-less mode

Cap-less mode is useful e.g. if the headphones are used as an antenna
for a FM radio, so that the signal is not altered. For everything else,
we want the cap-couple mode.

ASoC: codecs/jz4770: Adjust timeouts for cap-coupled outputs

When using cap-coupled outputs, the RUP/RDO can take much longer than
the 100ms timeout we used to have. Increase that timeout to one second.

In case a poll for RUP times out, we might be left with some IRQ flags

treewide: Use fallthrough pseudo-keyword

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

ASoC: codecs: merge .digital_mute() into .mute_stream()

snd_soc_dai_digital_mute() is internally using both
mute_stream() (1) or digital_mute() (2), but the difference between
these 2 are only handling direction.
We can merge digital_mute() into mute_stream

int snd_soc_dai_digital_mute(xxx, int direction)
{
...
else if (dai->driver->ops->mute_stream)
(1) return dai->driver->ops->mute_stream(xxx, direction);
else if (direction == SNDRV_PCM_STREAM_PLAYBACK &&
dai->driver->ops->digital_mute)
(2) return dai->driver->ops->digital_mute(xxx);
...
}

ASoC: ingenic: Unconditionally depend on devicetree

All boards with Ingenic SoCs probe with devicetree already, we have no
use for a non-devicetree path.

This solves some compilation warnings that were caused by unused
