VBLANK handlers in struct drm_driver are deprecated. Only legacy, non-KMS drivers are supposed to used them. DRM drivers with kernel modesetting are supposed to use VBLANK callbacks of the CRTC infrastructure. This patchset converts all DRM drivers to CRTC VBLANK callbacks and cleans up struct drm_driver. The remaining VBLANK callbacks in struct drm_driver are only used by legacy drivers. Patch

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 and 3 are enough to make the atmel-hlcdc driver do what I need (when patched
