+Rockchip RK3288 specific extensions to the Analogix Display Port
+================================
+
+Required properties:
+- compatible: "rockchip,rk3288-edp";
+
+- reg: physical base address of the controller and length
+
+- clocks: from common clock binding: handle to dp clock.
+	  of memory mapped region.
+
+- clock-names: from common clock binding:
+	       Required elements: "dp" "pclk"
+
+- resets: Must contain an entry for each entry in reset-names.
+	  See ../reset/reset.txt for details.
+
+- pinctrl-names: Names corresponding to the chip hotplug pinctrl states.
+- pinctrl-0: pin-control mode. should be <&edp_hpd>
+
+- reset-names: Must include the name "dp"
+
+- rockchip,grf: this soc should set GRF regs, so need get grf here.
+
+- ports: there are 2 port nodes with endpoint definitions as defined in
+  Documentation/devicetree/bindings/media/video-interfaces.txt.
+    Port 0: contained 2 endpoints, connecting to the ouput of vop.
+    Port 1: contained 1 endpoint, connecting to the input of panel.
+
+For the below properties, please refer to Analogix DP binding document:
+ * Documentation/devicetree/bindings/drm/bridge/analogix_dp.txt
+- phys (required)
+- phy-names (required)
+- hpd-gpios (optional)
+-------------------------------------------------------------------------------
+
+Example:
+	dp-controller: dp@ff970000 {
+		compatible = "rockchip,rk3288-dp";

+
+		rockchip,grf = <&grf>;
+		resets = <&cru 111>;
+		reset-names = "dp";
+
+		pinctrl-names = "default";
+		pinctrl-0 = <&edp_hpd>;
+
+		status = "disabled";
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+			edp_in: port@0 {
