This looks far too simplistic. There are different classes of DVI
connector - there is:
DVI A - analogue only
DVI D - digital only (single and dual link)
DVI I - both (single and dual digital link)
DRM at least makes a distinction between these three classes, and this
disctinction is part of the user API. How would a display system know
which kind of DVI connector is wired up on the board from this DT
description?
