[Intel-gfx] [PATCH v5 0/8] Skylake Y tiled scanout

[Tvrtko Ursulin]

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

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.

v5:
   * Addressed review comments in individual patches.
