The ADV7511, ADV7511W and ADV7513 are HDMI audio and video transmitters

The ADV7511, ADV7511W, ADV7513 and ADV7533 are HDMI audio and video transmitters

compatible with HDMI 1.4 and DVI 1.0. They support color space conversion,

S/PDIF, CEC and HDCP.

S/PDIF, CEC and HDCP. ADV7533 supports the DSI interface for input pixels, while

the others support RGB interface.



Required properties:



- compatible: Should be one of "adi,adv7511", "adi,adv7511w" or "adi,adv7513"

Required nodes:



The ADV7511 has two video ports. Their connections are modelled using the OF

graph bindings specified in Documentation/devicetree/bindings/graph.txt.



- Video port 0 for the RGB or YUV input

- Video port 0 for the RGB, YUV or DSI input. In the case of ADV7533, the
