These drivers are already not usable. I'm just making that obvious.

Precisely the point. It is pushing the problem to the sub-arches so they
can clean-up their stuff if they want to get into a multi-plat image. I
expect we will see some clean starting in parallel with this. The omap
folks are working omap headers and there were some clean-ups for Marvell
parts posted. Arnd has platform_data header series he is working on.
