[alsa-devel] [RESEND PATCH 0/4] ASoC: mediatek: mt8183-da7219: pick fixes from mt8183-mt6358

[Tzung-Bi Shih]

Cherry-picks fixes from mt8183-mt6358-ts3a227-max98357 machine driver.

The 1st patch from commit 1df1e5457cd1 ("ASoC: Mediatek: MT8183: change
supported formats of DL2 and UL1").

The 2nd patch from commit 6191cbde5ff0 ("ASoC: mediatek: mt8183: switch
tdm pins gpio function when playback on or off").

The 3rd patch from commit 8e58c521bcb8 ("ASoC: mediatek: mt8183: tdm hw
support tdm out and 8ch i2s out").

The 4th patch squashes the following:
- commit 63ba8e4d04ab ("ASoC: mediatek: mt8183: move card registration
  to the end of probe")
- commit 95d779b4b8e7 ("ASoC: mediatek: mt8183: move headset jack to
  card-specific storage")
- commit e5b3ae3e8c47 ("ASoC: mediatek: mt8183: fix space issues")

Changes from previous version:
(https://mailman.alsa-project.org/pipermail/alsa-devel/2020-February/162364.html)
- None, only rebase and resend.

I'll apply this but this feels like we might want to have some general
pinctrl integration, other devices could do something similar and might
achieve some power saving from it.

I have no idea what it could be so far.  But I am willing to help if
you have some draft ideas.

Off the top of my head if we have standard names for the states then we
could make DAPM widgets for the pinctrl stuff, probably like the
regulator supply ones since typically there's multiple AIF widgets per
physical interface.

I'll apply this but it feels like it should be at least two patches - if
you're writing a changelog with numbered changes like this it's a big
warning sign.

I see.  Will pay more attention and won't squash small changes next time.
