[alsa-devel] [PATCH 0/4] ASoC: mediatek: mt8183-da7219: pick fixes from mt8183-mt6358
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")
Tzung-Bi Shih (4): ASoC: mediatek: mt8183-da7219: change supported formats of DL2 and UL1 ASoC: mediatek: mt8183-da7219: pull TDM GPIO pins down when probed ASoC: mediatek: mt8183-da7219: support TDM out and 8ch I2S out ASoC: mediatek: mt8183-da7219: apply some refactors
