Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. Boris and Daniel, was this approximately what you had in mind? I have obviously not tested all of this with more than a compile, but the first patch is enough to make the atmel-hlcdc driver do what I need. The rest is just lots of removals and cleanup made possible by the improved core. Please test, I would not be surprised if I have fouled up some bit-manipulation somewhere in this mostly mechanical change...
