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?
Yes, I think that's a valid change. But do we also need to specify single/dual link, in addition to the three types?
I guess the compatible string is the easiest way for differentation, at least for the three main types, i.e. "dvi-d-connector" etc.
"dvi-d-1l-connector" and "dvi-d-2l-connector" for the single/dual link? That looks a bit funny.
