The VGA connector is described by a single input port and an optional DDC bus.
Wasn't there a generic connector binding for DVI, HDMI, etc.?
As far as I know, there are three separate generic bindings for DVI connectors, HDMI connectors, and analog TV connectors. The VGA connector doesn't seem to really fit into one of those categories.

A reference to the relevant video graph bindings should be added here.
I'll fix that.
