| 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 | }; |
