Subject: [PATCH v3 08/10] media: dt-bindings: Add Chameleon v3 video interface

Add dt binding for the video interface present on the Google
Chameleon v3. The Chameleon v3 uses the video interface to capture
a single video source from a given HDMI or DP connector and write
the resulting frames to memory.
