sii902x HDMI bridge bindings
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible: "sil,sii9022"
|
||||||
|
- reg: i2c address of the bridge
|
||||||
|
|
||||||
|
Optional properties:
|
||||||
|
- interrupts-extended or interrupt-parent + interrupts: describe
|
||||||
|
the interrupt line used to inform the host about hotplug events.
|
||||||
|
- reset-gpios: OF device-tree gpio specification for RST_N pin.
|
||||||
|
|
||||||
|
Optional subnodes:
|
||||||
|
- video input: this subnode can contain a video input port node
|
||||||
|
to connect the bridge to a display controller output (See this
|
||||||
|
documentation [1]).
|
||||||
|
|
||||||
|
[1]: Documentation/devicetree/bindings/media/video-interfaces.txt

Example:
|
||||||
|
hdmi-bridge@39 {
|
||||||
|
compatible = "sil,sii9022";
|
||||||
|
reg = <0x39>;
|

reset-gpios = <&pioA 1 0>;

ports {

#address-cells = <1>;

#size-cells = <0>;
