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.

v2:
* Refactor the series to use fb->modifier[0] directly at call sites
interested in tiling. (Daniel Vetter)

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

Tvrtko Ursulin (3):
drm/i915: Add tiled framebuffer modifiers
