- compatible : Can be one of the following,
|
|
"google,snow-audio-max98090" or
|
|
"google,snow-audio-max98091" or
|
|
"google,snow-audio-max98095"
|
|
- samsung,i2s-controller (deprecated): The phandle of the Samsung I2S controller
|
|
- samsung,audio-codec (deprecated): The phandle of the audio codec
|
|
|
|
Required sub-nodes:
|
|
|
|
- 'cpu' subnode with a 'sound-dai' property containing the phandle of the I2S
|
|
controller
|
|
- 'codec' subnode with a 'sound-dai' property containing list of phandles
|
|
to the CODEC nodes, first entry must be the phandle of the MAX98090,
|
|
MAX98091 or MAX98095 CODEC (exact device type is indicated by the compatible
|
|
string) and the second entry must be the phandle of the HDMI IP block node
|
|
|
|
Optional:
|
|
- samsung,model: The name of the sound-card
|
|
- codec-enable-gpio : The GPIO used to enable the audio codec
|
|
|
|
Example:
|
|
|
|
sound {
|
|
compatible = "google,snow-audio-max98095";
|
|
|
|
samsung,model = "Snow-I2S-MAX98095";
|
|
samsung,i2s-controller = <&i2s0>;
|
|
samsung,audio-codec = <&max98095>;
|
|
};
