Merge series "ASoC: mediatek: mt8183-da7219: support machine driver for rt1015" from Tzung-Bi Shih <tzungbi@google.com>:

This series tries to reuse mt8183-da7219-max98357.c for supporting machine
driver with rt1015 speaker amplifier.

The first 3 patches refactor the code for easier to change for subsequent
patches.

The 4th patch adds document for the new proposed compatible string.

The 5th patch changes the machine driver to support either "MAX98357A" or
"RT1015" codecs.

Tzung-Bi Shih (5):
  ASoC: mediatek: mt8183-da7219: sort header inclusions in alphabetical
  ASoC: mediatek: mt8183-da7219: remove forward declaration of
    headset_init
  ASoC: mediatek: mt8183-da7219: extract codec and DAI names
  ASoC: mediatek: mt8183-da7219: add compatible string for using rt1015
  ASoC: mediatek: mt8183-da7219: support machine driver with rt1015
