Merge tag 'drm-sii902x' of github.com:bbrezillon/linux-at91 into drm-next

Add basic support for the sii902x RGB -> HDMI bridge.

* tag 'drm-sii902x' of github.com:bbrezillon/linux-at91:
  drm/bridge: Add sii902x DT bindings doc
  drm/bridge: Add sii902x driver
parents 04d04051 b7eaa9ff
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>;
port@0 {
reg = <0>;
bridge_in: endpoint {
remote-endpoint = <&dc_out>;
};
};
};
};
