[Intel-gfx] [PATCH v2 0/8] Skylake 90/270 display rotation

[Tvrtko Ursulin]

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

Display engine on Skylake can scan out specially prepared frame buffers
rotated by 90 or 270 degrees.

This adds partial support for that - display programming patches are missing
from this initial posting because for now the only purpose is to see if people
now like the approach I have taken.

v2:
   * Individual review comments.
   * Main patch split into four smaller ones.

Tvrtko Ursulin (8):
  drm: Pass in new and old plane state to prepare_fb and cleanup_fb
  drm/i915/skl: Extract tile height code into a helper function
  drm/i915: Use GGTT view when (un)pinning objects to planes
  drm/i915: Pass in plane state when (un)pinning frame buffers
  drm/i915: Helper function to determine GGTT view from plane state
  drm/i915/skl: Support secondary (rotated) frame buffer mapping
  drm/i915/skl: Query display address through a wrapper
  drm/i915/skl: Take 90/270 rotation into account in watermark
    calculations
