Kernel-4.18.0-80.el8_mt8173-rt5650

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>;
    };
};
