MT8173 with RT5650 RT5676 CODECS
MT8173 with RT5650 RT5676 CODECS and HDMI via I2S
Required properties:
- compatible : "mediatek,mt8173-rt5650-rt5676"
- mediatek,audio-codec: the phandles of rt5650 and rt5676 codecs
and of the hdmi encoder node
- mediatek,platform: the phandle of MT8173 ASoC platform
Example:
sound {
compatible = "mediatek,mt8173-rt5650-rt5676";
mediatek,audio-codec = <&rt5650 &rt5676>;
mediatek,audio-codec = <&rt5650 &rt5676 &hdmi0>;
mediatek,platform = <&afe>;
};
