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?

-- FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly improving, and getting towards what was expected from it.
