While I agree that the GPMC driver is a bit messy, I'm not sure it's possible
to go through such a complete devicetree binding re-design (breaking backwards
compatibility) now that the binding is already in production.

AFAIK, TI's SDK 7.0 is released, with a v3.8.x kernel which uses this GPMC
binding. And then you have the ISEE board too, using this binding.

Also, what's the problem with the current devicetree binding (not that I'm fan
of it)?
