+Rockchip RV1108 RGB interface
+================================
+
+Required properties:
+- compatible: matching the soc type:
+ - "rockchip,rv1108-rgb";
+
+Optional properties:
+- pinctrl-names: must contain a "lcdc" entry.
+- pinctrl-0: pin control group to be used for this interface.
+
+Required nodes:
+- rockchip,rgb-mode: should be "p888", "p666", "p565", "s888", "s888-dummy"
This should be a standard property. Any device with a parallel interface
is going to need something like this.
so, i need to move this property to panel? or just rename
rockchip,rgb-mode to rgb-mode?
+ - p888: output r8-g8-b8 at each dclk cycle for per-pixel
+ - p666: output r6-g6-b6 at each dclk cycle for per-pixel
+ - p565: output r5-g6-b5 at each dclk cycle for per-pixel
+ - s888: output r8-g8-b8 in three dclk cycle for per-pixel
+ - s888-dmmy: output r8-g8-b8-dummy in four dclk cycle for per-pixel
+
+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>;
+ rockchip,rgb-mode = "p888";
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ rgb_in: port@0 {
+ reg = <0>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ rgb_in_vop: endpoint@0 {
+ reg = <0>;
Don't need reg for a single endpoint.
ok, this will be deleted at next version.
+ remote-endpoint = <&vop_out_rgb>;
+ };
+ };
+
+ rgb_out: port@1 {
+ reg = <1>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ rgb_out_panel: endpoint@0 {
+ reg = <0>;
ditto.
ok, this will be deleted at next version.
+ remote-endpoint = <&panel_in_rgb>;
+ };
+ };
+ };
+ };
