Feel free to add an Acked-by: Christian König <christian.koenig@xxxxxxx>
to all patches which I haven't explicitly reviewed.
I would say we should just push this to drm-misc-next now.
Thanks for the nice cleanup,
Christian.

The GEM and PRIME related callbacks in struct drm_driver are deprecated in
favor of GEM object functions in struct drm_gem_object_funcs. This patchset
converts the remaining drivers to object functions and removes most of the
obsolete interfaces.
Version 3 of this patchset mostly fixes drm_gem_prime_handle_to_fd and
updates i.MX's dcss driver. The driver was missing from earlier versions
and still needs review.
Patches #1 to #6, #8 to #17 and #19 to #20 convert DRM drivers to GEM object
functions, one by one. Each patch moves existing callbacks from struct
drm_driver to an instance of struct drm_gem_object_funcs, and sets these
funcs when the GEM object is initialized. The expection is .gem_prime_mmap.
There are different ways of how drivers implement the callback, and moving
it to GEM object functions requires a closer review for each.
Patch #18 fixes virtgpu to use GEM object functions where possible. The
driver recently introduced a function for one of the deprecated callbacks.
Patches #7 and #20 convert i.MX's dcss and xlnx to CMA helper macros. There's
no apparent reason why the drivers do the GEM setup on their's own. Using CMA
helper macros adds GEM object functions implicitly.
With most of the GEM and PRIME moved to GEM object functions, related code
in struct drm_driver and in the DRM core/helpers is being removed by patch
#22.
Further testing is welcome. I tested the drivers for which I have HW
available. These are gma500, i915, nouveau, radeon and vc4. The console,
Weston and Xorg apparently work with the patches applied.
v3:
* restore default call to drm_gem_prime_export() in
drm_gem_prime_handle_to_fd()
* return -ENOSYS if get_sg_table is not set
* drop all checks for obj->funcs
* clean up TODO list and documentation
v2:
* moved code in amdgpu and radeon
* made several functions static in various drivers
* updated TODO-list item
* fix virtgpu
