MT8173 with RT5650 CODECS and HDMI via I2S
Required properties:
- compatible : "mediatek,mt8173-rt5650"
- mediatek,audio-codec: the phandles of rt5650 codecs
and of the hdmi encoder node
- mediatek,platform: the phandle of MT8173 ASoC platform
Optional subnodes:
- codec-capture : the subnode of rt5650 codec capture
Required codec-capture subnode properties:
- sound-dai: audio codec dai name on capture path
<&rt5650 0> : Default setting. Connect rt5650 I2S1 for capture. (dai_name = rt5645-aif1)
<&rt5650 1> : Connect rt5650 I2S2 for capture. (dai_name = rt5645-aif2)
- mediatek,mclk: the MCLK source
0 : external oscillator, MCLK = 12.288M
1 : internal source from mt8173, MCLK = sampling rate*256
Example:
sound {
compatible = "mediatek,mt8173-rt5650";
mediatek,audio-codec = <&rt5650 &hdmi0>;
mediatek,platform = <&afe>;
mediatek,mclk = <0>;
codec-capture {
sound-dai = <&rt5650 1>;
};
};
