Device Tree bindings for the Armada 370 DB audio
|
||||
================================================
|
||||
|
||||
These Device Tree bindings are used to describe the audio complex
|
||||
found on the Armada 370 DB platform.
|
||||
|
||||
Mandatory properties:
|
||||
|
||||
* compatible: must be "marvell,a370db-audio"
|
||||
|
||||
* marvell,audio-controller: a phandle that points to the audio
|
||||
controller of the Armada 370 SoC.
|
||||
|
||||
* marvell,audio-codec: a phandle that points to the analog audio
|
||||
codec connected to the Armada 370 SoC.
|
||||
|
||||
Example:
|
||||
|
||||
sound {
|
||||
compatible = "marvell,a370db-audio";
|
||||
marvell,audio-controller = <&audio_controller>;
|
||||
marvell,audio-codec = <&audio_codec>;
|
||||
status = "okay";
|
||||
};

"marvell,armada370-audio" for Armada 370 platforms
