Merge series "ASoC: mediatek: mt8183: support DP audio" from Tzung-Bi Shih <tzungbi@google.com>:

This series is a follow up for a long time ago series
(https://patchwork.kernel.org/cover/11204303/).

The old series bound too much on the patches of DRM bridge and ASoC
machine driver.  And unluckily, the dependencies
(https://lore.kernel.org/patchwork/patch/1126819/) have not applied.

Revewing the ASoC patches in the old series, I found that they could be
decoupled from the DRM bridge patches.  And they are harmless as it is
an optional attribute ("hdmi-codec") in DTS.

This series arranges and rebases the harmless ASoC patches for
mt8183-mt6358-ts3a227-max98357 and mt8183-da7219-max98357.

The 1st and 4th patch add an optional DT property.  The 1st patch was
acked long time ago (https://patchwork.kernel.org/patch/11204321/).

The 2nd and 5th patch add DAI link for using hdmi-codec.

The 3rd and 6th patch support the HDMI jack reporting.

Tzung-Bi Shih (6):
  ASoC: dt-bindings: mt8183: add a property "mediatek,hdmi-codec"
  ASoC: mediatek: mt8183: use hdmi-codec
  ASoC: mediatek: mt8183: support HDMI jack reporting
  ASoC: dt-bindings: mt8183-da7219: add a property "mediatek,hdmi-codec"
  ASoC: mediatek: mt8183-da7219: use hdmi-codec
  ASoC: mediatek: mt8183-da7219: support HDMI jack reporting
