Device-Tree bindings for dummy HDMI codec
|
||||
|
||||
Required properties:
|
||||
- compatible: should be "linux,hdmi-audio".
|
||||
|
||||
CODEC output pins:
|
||||
* TX
|
||||
|
||||
CODEC input pins:
|
||||
* RX
|
||||
|
||||
Example node:
|
||||
|
||||
hdmi_audio: hdmi_audio@0 {
|
||||
compatible = "linux,hdmi-audio";
|
||||
status = "okay";
|
