+* 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>;
+ };
+ };
+ };
