* 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>;
		};
		...
	};
