16*4882a593Smuzhiyun
17*4882a593SmuzhiyunThe ADV7125 has two video ports. Their connections are modeled using the OF
18*4882a593Smuzhiyungraph bindings specified in Documentation/devicetree/bindings/graph.txt.
19*4882a593Smuzhiyun
20*4882a593Smuzhiyun- Video port 0 for RGB input
21*4882a593Smuzhiyun- Video port 1 for VGA output
