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