MT8173 with RT5650 RT5514 CODECS
|
||||
|
||||
Required properties:
|
||||
- compatible : "mediatek,mt8173-rt5650-rt5514"
|
||||
- mediatek,audio-codec: the phandles of rt5650 and rt5514 codecs
|
||||
- mediatek,platform: the phandle of MT8173 ASoC platform
|
||||
|
||||
Example:
|
||||
|
||||
sound {
|
||||
compatible = "mediatek,mt8173-rt5650-rt5514";
|
||||
mediatek,audio-codec = <&rt5650 &rt5514>;
|

mediatek,platform = <&afe>;
