+* Analog Devices ADV7604/11 video decoder with HDMI receiver
+
+The ADV7604 and ADV7611 are multiformat video decoders with an integrated HDMI
+receiver. The ADV7604 has four multiplexed HDMI inputs and one analog input,
+and the ADV7611 has one HDMI input and no analog input.
+
+These device tree bindings support the ADV7611 only at the moment.
+
+Required Properties:
+
+ - compatible: Must contain one of the following
+ - "adi,adv7611" for the ADV7611
+
+ - reg: I2C slave address
+
+ - hpd-gpios: References to the GPIOs that control the HDMI hot-plug
+ detection pins, one per HDMI input. The active flag indicates the GPIO
+ level that enables hot-plug detection.
+
+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.
+
+ Port ADV7611
+------------------------------------------------------------
+ HDMI 0
+ Digital output 1
+
+The digital output port node must contain at least one endpoint.
+
+Optional Properties:
+
+ - reset-gpios: Reference to the GPIO connected to the device's reset pin.
+
+Optional Endpoint Properties:
+
+ The following three properties are defined in video-interfaces.txt and are
+ valid for source endpoints only.
+
+ - hsync-active: Horizontal synchronization polarity. Defaults to active low.
+ - vsync-active: Vertical synchronization polarity. Defaults to active low.
+ - pclk-sample: Pixel clock polarity. Defaults to output on the falling edge.
+
+ If none of hsync-active, vsync-active and pclk-sample is specified the
+ endpoint will use embedded BT.656 synchronization.
+
+
+Example:
+
+ hdmi_receiver@4c {
+ compatible = "adi,adv7611";
+ reg = <0x4c>;
+
+ reset-gpios = <&ioexp 0 GPIO_ACTIVE_LOW>;
+ hpd-gpios = <&ioexp 2 GPIO_ACTIVE_HIGH>;
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+ };
+ port@1 {
+ reg = <1>;
+ hdmi_in: endpoint {
+ remote-endpoint = <&ccdc_in>;
+ };
+ };
+ };
