* 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 addresses
    The ADV748x has up to twelve 256-byte maps that can be accessed via the
    main I2C ports. Each map has it own I2C address and acts as a standard
    slave device on the I2C bus. The main address is mandatory, others are
    optional and remain at default values if not specified.

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
  - reg-names : Names of maps with programmable addresses.
		It shall contain all maps needing a non-default address.
		Possible map names are:
		  "main", "dpll", "cp", "hdmi", "edid", "repeater",
		  "infoframe", "cbus", "cec", "sdp", "txa", "txb"

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 0x71 0x72 0x73 0x74 0x75
		       0x60 0x61 0x62 0x63 0x64 0x65>;
		reg-names = "main", "dpll", "cp", "hdmi", "edid", "repeater",
			    "infoframe", "cbus", "cec", "sdp", "txa", "txb";

		#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@a {
			reg = <10>;

			adv7482_txa: endpoint {
				clock-lanes = <0>;
				data-lanes = <1 2 3 4>;
				remote-endpoint = <&csi40_in>;
			};
		};

		port@b {
			reg = <11>;

			adv7482_txb: endpoint {
				clock-lanes = <0>;
				data-lanes = <1>;
				remote-endpoint = <&csi20_in>;
			};
		};
	};
