media: adv748x: Add adv7481, adv7482 bindings 



Create device tree bindings documentation for the ADV748x.
The ADV748x supports both the ADV7481 and ADV7482 chips which
provide analogue decoding and HDMI receiving capabilities

* Analog Devices ADV748X video decoder with HDMI receiver



The ADV7481 and ADV7482 are multi format video decoders with an integrated

HDMI receiver. They can output CSI-2 on two independent outputs TXA and TXB

from three input sources HDMI, analog and TTL.



Required Properties:



  - compatible: Must contain one of the following

    - "adi,adv7481" for the ADV7481

    - "adi,adv7482" for the ADV7482



  - reg: I2C slave address



Optional Properties:



  - interrupt-names: Should specify the interrupts as "intrq1", "intrq2" and/or

		     "intrq3". All interrupts are optional. The "intrq3" interrupt

		     is only available on the adv7481

  - interrupts: Specify the interrupt lines for the ADV748x



The device node must contain one 'port' child node per device input and output

port, in accordance with the video interface bindings defined in

Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes

are numbered as follows.



	  Name		Type		Port

	---------------------------------------

	  AIN0		sink		0

	  AIN1		sink		1

	  AIN2		sink		2

	  AIN3		sink		3

	  AIN4		sink		4

	  AIN5		sink		5

	  AIN6		sink		6

	  AIN7		sink		7

	  HDMI		sink		8

	  TTL		sink		9

	  TXA		source		10

	  TXB		source		11



The digital output port nodes must contain at least one endpoint.



Ports are optional if they are not connected to anything at the hardware level.



Example:



	video-receiver@70 {

		compatible = "adi,adv7482";

		reg = <0x70>;



		#address-cells = <1>;

		#size-cells = <0>;



		interrupt-parent = <&gpio6>;

		interrupt-names = "intrq1", "intrq2";

		interrupts = <30 IRQ_TYPE_LEVEL_LOW>,

			     <31 IRQ_TYPE_LEVEL_LOW>;



		port@7 {

			reg = <7>;



			adv7482_ain7: endpoint {

				remote-endpoint = <&cvbs_in>;

			};

		};



		port@8 {

			reg = <8>;



			adv7482_hdmi: endpoint {

				remote-endpoint = <&hdmi_in>;

			};

		};



		port@10 {

			reg = <10>;



			adv7482_txa: endpoint {

				clock-lanes = <0>;

				data-lanes = <1 2 3 4>;

				remote-endpoint = <&csi40_in>;

			};

		};



		port@11 {

			reg = <11>;



			adv7482_txb: endpoint {

				clock-lanes = <0>;

				data-lanes = <1>;

				remote-endpoint = <&csi20_in>;

			};

		};

	};
