-Rockchip RK3288 LVDS interface
-================================
-
-Required properties:
-- compatible: matching the soc type, one of
- - "rockchip,rk3288-lvds";
- - "rockchip,px30-lvds";
-
-- reg: physical base address of the controller and length
- of memory mapped region.
-- clocks: must include clock specifiers corresponding to entries in the
- clock-names property.
-- clock-names: must contain "pclk_lvds"
-
-- avdd1v0-supply: regulator phandle for 1.0V analog power
-- avdd1v8-supply: regulator phandle for 1.8V analog power
-- avdd3v3-supply: regulator phandle for 3.3V analog power
-
-- rockchip,grf: phandle to the general register files syscon
-- rockchip,output: "rgb", "lvds" or "duallvds", This describes the output interface
-
-- phys: LVDS/DSI DPHY (px30 only)
-- phy-names: name of the PHY, must be "dphy" (px30 only)
-
-Optional properties:
-- pinctrl-names: must contain a "lcdc" entry.
-- pinctrl-0: pin control group to be used for this controller.
-
-Required nodes:
-
-The lvds has two video ports as 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 or vopl
-- video port 1 for either a panel or subsequent encoder
-
-Example:
-
-lvds_panel: lvds-panel {
- compatible = "auo,b101ean01";
- enable-gpios = <&gpio7 21 GPIO_ACTIVE_HIGH>;
- data-mapping = "jeida-24";
-
- ports {
- panel_in_lvds: endpoint {
- remote-endpoint = <&lvds_out_panel>;
- };
- };
-};
-
-For Rockchip RK3288:
-
- lvds: lvds@ff96c000 {
- compatible = "rockchip,rk3288-lvds";
- rockchip,grf = <&grf>;
- reg = <0xff96c000 0x4000>;
- clocks = <&cru PCLK_LVDS_PHY>;
- clock-names = "pclk_lvds";
- pinctrl-names = "lcdc";
- pinctrl-0 = <&lcdc_ctl>;
- avdd1v0-supply = <&vdd10_lcd>;
- avdd1v8-supply = <&vcc18_lcd>;
- avdd3v3-supply = <&vcca_33>;
- rockchip,output = "rgb";
- ports {
- #address-cells = <1>;
- #size-cells = <0>;
-
- lvds_in: port@0 {
- reg = <0>;
-
- lvds_in_vopb: endpoint@0 {
- reg = <0>;
- remote-endpoint = <&vopb_out_lvds>;
- };
- lvds_in_vopl: endpoint@1 {
- reg = <1>;
- remote-endpoint = <&vopl_out_lvds>;
- };
- };
-
- lvds_out: port@1 {
- reg = <1>;
-
- lvds_out_panel: endpoint {
- remote-endpoint = <&panel_in_lvds>;
- };
- };
- };
- };
