drm/tve200: Add DT bindings 



This adds device tree bindings for the Faraday TVE200 IP block.
This IP block is present in the Gemini ARM SoC and also in some
Grain Media GMxxxx SoCs.

* Faraday TV Encoder TVE200



Required properties:



- compatible: must be one of:

	"faraday,tve200"

	"cortina,gemini-tvc", "faraday,tve200"



- reg: base address and size of the control registers block



- interrupts: contains an interrupt specifier for the interrupt

	line from the TVE200



- clock-names: should contain "PCLK" for the clock line clocking the

	silicon and "TVE" for the 27MHz clock to the video driver



- clocks: contains phandle and clock specifier pairs for the entries

	in the clock-names property. See

	Documentation/devicetree/bindings/clock/clock-bindings.txt



Optional properties:



- resets: contains the reset line phandle for the block



Required sub-nodes:



- port: describes LCD panel signals, following the common binding

	for video transmitter interfaces; see

	Documentation/devicetree/bindings/media/video-interfaces.txt

	This port should have the properties:

	reg = <0>;

	It should have one endpoint connected to a remote endpoint where

	the display is connected.



Example:



display-controller@6a000000 {

	#address-cells = <1>;

	#size-cells = <0>;

	compatible = "faraday,tve200";

	reg = <0x6a000000 0x1000>;

	interrupts = <13 IRQ_TYPE_EDGE_RISING>;

	resets = <&syscon GEMINI_RESET_TVC>;

	clocks = <&syscon GEMINI_CLK_GATE_TVC>,

		 <&syscon GEMINI_CLK_TVC>;

	clock-names = "PCLK", "TVE";



	port@0 {

		reg = <0>;

		display_out: endpoint {

			remote-endpoint = <&panel_in>;

		};

	};

};
