From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
Start using frame buffer modifiers instead of object tiling mode
for display purposes.
To ensure compatibility with old userspace which is using set_tiling
and does not know about frame buffer modifiers, the latter are faked
internally when tile object is set for display. This way all interested
call sites can use fb modifiers exclusively.
Also ensure tiling specified via fb modifiers must match object tiling
used for fencing if both are specified.
v2:
* Refactored to use fb modifiers directly in switch statements in
order to completely disconnect from the object tiling namespace.
(Daniel Vetter)
* Added helper to convert to hardware mode representation for
future proofing.
v3:
* Simplified old vs new userspace logic flow.
* Reject zero fb modifier when flag is set.
* Correct pitch_limit checks.
