+- clock-names: from common clock binding:

+
+- 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.
