That's pretty much what I've come up with in the second round of Tegra DRM
patches. Basically display controllers and outputs (RGB, HDMI, TVO, DSI) get
separate drivers and register themselves with the DRM driver which then looks
at the device tree to see which display controllers to register as CRTCs and
parses a list of connector nodes to create encoder/connector pairs that
define the physical connectors and their corresponding outputs.

I did take a brief look at the SDRM patches as well and they didn't quite
seem to fit what was needed for Tegra. But if time allows I'll take a closer
