From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Instead of using driver private set tiling ioctl, use the proposed addfb2 ioctl
extension to tell the driver about display buffer special formatting.

Lightly tested only with a hacked up igt/testdisplay. Sending out early so
people can comment on the overall approach over the weekend.

Rob Clark (1):
RFC: drm: add support for tiled/compressed/etc modifier in addfb2
