    1 MT8173 with RT5650 CODECS and HDMI via I2S
    2 
    3 Required properties:
    4 - compatible : "mediatek,mt8173-rt5650"
    5 - mediatek,audio-codec: the phandles of rt5650 codecs
    6                         and of the hdmi encoder node
    7 - mediatek,platform: the phandle of MT8173 ASoC platform
    8 
    9 Optional subnodes:
   10 - codec-capture : the subnode of rt5650 codec capture
   11 Required codec-capture subnode properties:
   12 - sound-dai: audio codec dai name on capture path
   13   <&rt5650 0> : Default setting. Connect rt5650 I2S1 for capture. (dai_name = rt5645-aif1)
   14   <&rt5650 1> : Connect rt5650 I2S2 for capture. (dai_name = rt5645-aif2)
   15 
   16 - mediatek,mclk: the MCLK source
   17   0 : external oscillator, MCLK = 12.288M
   18   1 : internal source from mt8173, MCLK = sampling rate*256
   19 
   20 Example:
   21 
   22         sound {
   23                 compatible = "mediatek,mt8173-rt5650";
   24                 mediatek,audio-codec = <&rt5650 &hdmi0>;
   25                 mediatek,platform = <&afe>;
   26                 mediatek,mclk = <0>;
   27                 codec-capture {
   28                         sound-dai = <&rt5650 1>;
   29                 };
   30         };
