The Armada 370 DB board not only has analog audio input/output, but also S/PDIF input/output. This commit adds support for S/PDIF in the ASoC machine driver of the Armada 370 DB platform, and adjusts the Device Tree bindings documentation accordingly.

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 set of three phandles that points to:
|
|
|
|
1/ the analog audio codec connected to the Armada 370 SoC
|
|
2/ the S/PDIF transceiver
|
|
3/ the S/PDIF receiver
|
|
|
|
Example:
|
|
|
|
sound {
|
|
compatible = "marvell,a370db-audio";
|
|
marvell,audio-controller = <&audio_controller>;
|
|
marvell,audio-codec = <&audio_codec &spdif_out &spdif_in>;
|
|
status = "okay";
|
|
};
