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. I have obviously not tested all of this with more than a compile, but patches 1 through 5 are enough to make the atmel-hlcdc driver do what I need. The rest

Hi all, First thing first: It works, I now no longer have a few dropped frames every 10s on my testbox here with the pageflip i-g-t tests. Random notes: - New design has per-crtc locks to protect the crtc input-side (pageflip, cursor) for r/w and the output state of the crtc (mode, dpms) as read-only. It also required completely revamped fb lifecycle management, those are now refcounted
