+Rockchip RK3399 specific extensions to the cdn Display Port
+================================
+
+Required properties:
+- compatible: must be "rockchip,cdn-dp"
+
+- reg: physical base address of the controller and length
+
+- clocks: from common clock binding: handle to dp clock.
+
+- clock-names: from common clock binding:
+ Required elements: "core_clk" "pclk" "spdif"
+
+- rockchip,grf: this soc should set GRF regs, so need get grf here.
+
+- ports: contain a port nodes with endpoint definitions as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt.
+ contained 2 endpoints, connecting to the output of vop.
+
+- phys: from general PHY binding: the phandle for the PHY device.
+
+- extcon: extcon specifier for the Power Delivery
+
+- #sound-dai-cells = it must be 1 if your system is using 2 DAIs: I2S, SPDIF
+
+-------------------------------------------------------------------------------
+
+Example:
+ cdn_dp: dp@fec00000 {
+ compatible = "rockchip,cdn-dp";
+ reg = <0x0 0xfec00000 0x0 0x100000>;
+ interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&cru SCLK_DP_CORE>, <&cru PCLK_DP_CTRL>,
