the same driver 5 times, and while the Silicon Image controllers are
wonderfully generic with a common API ("TPI") and there could be a
generic MFD solution with shim drivers on top for DRM, nobody else's
are quite as nice.

I got here and immediately thought "oh god not more layers to DRM".
DRM does _not_ need any more bloody layers on top of the existing
layers.  It needs a library of helper functions to provide common
functionality so that folk don't have to write the same bloody stuff
time and time again.

A library of helpers, not a shim layer to convert it to something else.
