[Intel-gfx] [PATCH 0/2] Add NV12 90/270 support for skl planes

[Chandra Konduru]

First attempt to enabling 90/270 rotation for NV12 format using Tvrtko's
recent rotated mapping for NV12.

Calling intel_plane_obj_offset(plane, obj, 1) is causing kernel NULL
pointer reference. Sending early out early for Tvrtko to work on the
issue.

Very first NV12 flip with 90/270 rotation giving rotated image but
UV isn't there because of above issue. Also subsequent flips are causing
crashes and lockups.

Pending work:
 * few changes are need to DDB calcuations for NV12 90/270.

Chandra Konduru (2):
  drm/i915: call intel_tile_height with correct parameter
  drm/i915: Add 90/270 rotation for NV12 format.
