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 };
