[Intel-gfx] [PATCH 0/7] 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.

Damien Lespiau (4):
  drm/i915/skl: Allow scanning out Y and Yf fbs
  drm/i915/skl: Adjust intel_fb_align_height() for Yb/Yf tiling
  drm/i915/skl: Teach pin_and_fence_fb_obj() about Y tiling constraints
  drm/i915/skl: Adjust get_plane_config() to support Yb/Yf tiling

Tvrtko Ursulin (3):
  drm/i915/skl: Add new displayable tiling formats
  drm/i915/skl: Update watermarks for Y tiling
  drm/i915/skl: Allow Y (and Yf) frame buffer creation
