Changes:
- use data-mapping instead of rockchip,data-mapping and rockchip,data-width
- move rockchip,output to lvds node

+Rockchip RK3288 LVDS interface
+================================
+
+Required properties:
+- compatible: matching the soc type, one of
+ - "rockchip,rk3288-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 face.
s/face/interface/
thanks, this will be fix at next version;
+
+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 inputs
with 2 endpoints...
yes, lvds port0 remote endpoint maybe vopb or vopl, i will add this
describe at next version.
+- video port 1 for either a panel or subsequent encoder
+
+the lvds panel described by
+ Documentation/devicetree/bindings/display/panel/simple-panel.txt
+
+Panel required properties:
+- ports for remote LVDS output
+
+Panel optional properties:
+- data-mapping: should be "vesa-24","jeida-24" or "jeida-18".
+This describes decribed by:
+ Documentation/devicetree/bindings/display/panel/panel-lvds.txt
+
+Example:
+
+lvds_panel: lvds-panel {
+ status = "okay";
Don't show status in examples.
thanks, this will be fix at next version;
+ compatible = "auo,b101ean01";
