From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
Starting with Skylake the display engine can scan out Y tiled objects. (Both
legacy Y tiled, and the new Yf format.)
This series takes the original work by Damien Lespiau and converts it to use the
new frame buffer modifiers instead of object set/get tiling. Some patches needed
to be dropped, some added and some refactored.
Lightly tested with "testdisplay -m -y" and "testdisplay -m --yf".
v2: Rebased on v2 of "i915 fb modifier support, respun".
v3:
* Part which allows Y tiled fb creation extracted out and moved to the end
of series.
* Dropped redundant "drm/i915/skl: Allow Y tiling for sprites".
* Also see individual change logs.
v4:
* New to the series - watermark programming updates per BSpec.
* Addressed review comments in individual patches.
