Merge series "ASoC: mediatek: mt8192-mt6359: support DP audio" from T…

…zung-Bi Shih <tzungbi@google.com>:

The 1st and 2nd patches refactor the machine driver.

The 3rd patch changes the platform driver to support TDM 8 channel output.

The 4th patch adds an optional DT property.

The 5th patch makes the machine driver support DP audio if the optional DT
property is specified.

Tzung-Bi Shih (5):
  ASoC: mediatek: mt8192-mt6359: move headset_jack to card specific data
  ASoC: mediatek: mt8192-mt6359: simplify mt8192_rt5682_init
  ASoC: mediatek: mt8192: change mclk_multiple of TDM from 128 to 512
  ASoC: dt-bindings: mt8192-mt6359: add hdmi-codec property
  ASoC: mediatek: mt8192-mt6359: support audio over DP
