This patch adds basic support for the ADV7482. It can output the HDMI
source on the TXA sink and any AIN source on the TXB sink.
Driver is based on a prototype by Koji Matsuoka in the Renesas BSP.

+* Analog Devices ADV7482 video decoder with HDMI receiver
+
+The ADV7482 are a multi format video decoders with an integrated
+HDMI receiver. It 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,adv7482" for the ADV7482
+
+ - reg: I2C slave address
+
+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
+------------------------------------------------------------
+ HDMI sink 0
+ AIN1 sink 1
+ AIN sink 2
+ AIN sink 3
+ AIN sink 4
+ AIN sink 5
+ AIN sink 6
+ AIN sink 7
+ AIN sink 8
+ TTL sink 9
+ TXA source 10
+ TXB source 11
+
+The digital output port node must contain at least one source endpoint.
+
+Example:
+
+ video_receiver@70 {
+ compatible = "adi,adv7482";
+ reg = <0x70>;
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@10 {
+ reg = <10>;
+ adv7482_txa: endpoint@1 {
+ clock-lanes = <0>;
+ data-lanes = <1 2 3 4>;
+ remote-endpoint = <&csi40_in>;
+ };
+ };
+
+ port@11 {
+ reg = <11>;
+ adv7482_txb: endpoint@1 {
+ clock-lanes = <0>;
+ data-lanes = <1>;
+ remote-endpoint = <&csi20_in>;
+ };
+ };
+ };
