Merge series "ASoC: mediatek: mt8183: support machine driver for max98357b" from Tzung-Bi Shih <tzungbi@google.com>:
The series re-uses mt8183-mt6358-ts3a227-max98357.c to support machine driver with max98357b. The 1st patch enables left justified format from mt8183 audio platform. The 2nd patch adds document for the new proposed compatible string for max98357b. The 3rd patch supports machine driver with max98357b and uses left justified format for it. Tzung-Bi Shih (3): ASoC: mediatek: mt8183: support left justified format for I2S ASoC: dt-bindings: mt8183: add compatible string for using max98357b ASoC: mediatek: mt8183: support machine driver with max98357b .../sound/mt8183-mt6358-ts3a227-max98357.txt | 1 + sound/soc/mediatek/mt8183/mt8183-dai-i2s.c | 59 ++++++++++++++++--- .../mt8183/mt8183-mt6358-ts3a227-max98357.c | 22 ++++++- 3 files changed, 73 insertions(+), 9 deletions(-) -- 2.28.0.rc0.105.gf9edc3c819-goog
