+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
