   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
