Merge series "ASoC: Mediatek: Add support for MT8192 SoC" from Jiaxin Yu <jiaxin.yu@mediatek.com>:

This series of patches adds support for Mediatek AFE for MT8192 SoC. At the same
time, the calibration function of MT6359 is completed with real machine driver.
The patch is based on broonie tree "for-next" branch.

Change since v3:
  - use normal conditional statements to improve legiblity in [v3,3/9]
  - remove mtk_i2s_hd_en_event as there's trace in the core
  - impove mt8192_i2s_enum and mt8192_adda_enum

Change since v2:
  - split the dai driver files as a separate patch
  - fix dt-bindings to GPL-2.0-only License
  - remove unnecessary preperty descriptions such as 'maxItems'

Change since v1:
  - fixed some typos related to dt-bindings in [v1,3/5] and [v1,5/5]
  - add vendor prefix to the properties, such as "mediatek,apmixedsys"
  - add a dependency description to indicate the required header files

Jiaxin Yu (9):
  ASoC: mediatek: mt6359: add the calibration functions
  ASoC: mediatek: mt8192: add platform driver
  ASoC: mediatek: mt8192: support i2s in platform driver
  ASoC: mediatek: mt8192: support adda in platform driver
  ASoC: mediatek: mt8192: support pcm in platform driver
  ASoC: mediatek: mt8192: support tdm in platform driver
  dt-bindings: mediatek: mt8192: add audio afe document
  ASoC: mediatek: mt8192: add machine driver with mt6359, rt1015 and
    rt5682
  dt-bindings: mediatek: mt8192: add mt8192-mt6358-rt1015-rt5682
