+Rockchip RV1108 RGB interface
+================================
+
+Required properties:
+- compatible: matching the soc type:
+ - "rockchip,px30-rgb";
+ - "rockchip,rv1108-rgb";
+
+Optional properties:
+- pinctrl-names: should be a "lcdc" entry or a "default" entry.
+- pinctrl-0: pin control group to be used for this interface.
+
+The rgb has two video ports described by:
+ Documentation/devicetree/bindings/media/video-interfaces.txt
+Their connections are modeled using the OF graph bindings specified in
+ Documentation/devicetree/bindings/graph.txt.
+
+- video port 0 for the VOP input, the remote endpoint maybe vopb/vopl/vop
+- video port 1 for either a panel or subsequent encoder
+
+the panel described by:
+ Documentation/devicetree/bindings/display/panel/simple-panel.txt
+Panel other required properties:
+- ports for remote rgb output.
+
+Example:
+
+panel: panel {
+ compatible = "auo,b101ean01";
+ enable-gpios = <&gpio7 21 GPIO_ACTIVE_HIGH>;
+
+ ports {
+ panel_in_rgb: endpoint {
+ remote-endpoint = <&rgb_out_panel>;
+ };
+ };
+};
+
+For Rockchip RV1108:
+
+ rgb: rgb {
+ compatible = "rockchip,rv1108-rgb";
+ pinctrl-names = "lcdc";
+ pinctrl-0 = <&lcdc_ctl>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ rgb_in: port@0 {
+ reg = <0>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ rgb_in_vop: endpoint {
+ remote-endpoint = <&vop_out_rgb>;
+ };
+ };
+
+ rgb_out: port@1 {
+ reg = <1>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ rgb_out_panel: endpoint {
+ remote-endpoint = <&panel_in_rgb>;
+ };
+ };
+ };
+ };
