* Analog Devices ADV7180 analog video decoder family

The adv7180 family devices are used to capture analog video to different

digital interfaces like MIPI CSI-2 or parallel video.

Required Properties :

- compatible : value must be one of

		"adi,adv7180"

		"adi,adv7180cp"

		"adi,adv7180st"

		"adi,adv7182"

		"adi,adv7280"

		"adi,adv7280-m"

		"adi,adv7281"

		"adi,adv7281-m"

		"adi,adv7281-ma"

		"adi,adv7282"

		"adi,adv7282-m"

Device nodes of "adi,adv7180cp" and "adi,adv7180st" 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		adv7180cp	adv7180st

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

  Input		0-2		0-5

  Output	3		6

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

Optional Properties :

- powerdown-gpios: reference to the GPIO connected to the powerdown pin,

  if any.

Example:

	i2c0@1c22000 {

		...

		...

		adv7180@21 {

			compatible = "adi,adv7180";

			reg = <0x21>;

		};

		...

	};
