First attempt at rotated GGTT mapping for the NV12 format.
It compiles and even does not crash on first use. But some parts are
probably too simplistic at the moment and need further polish.
Sending out early since Chandra needs this to complete his display
programming patches.
Depends on Chandra's NV12 patch series.
Tvrtko Ursulin (8):
drm/i915: Remove duplicated intel_tile_height declaration
drm/i915: Support planar formats in tile height calculations
drm/i915: Remove pointless calculation in intel_rotate_fb_obj_pages
drm/i915: Extract tiled geometry calculation into a helper function
drm/i915: Support appending to the rotated pages mapping
drm/i915: Support NV12 in rotated GGTT mapping
drm/i915: Enable querying offset of UV plane with
intel_plane_obj_offset
drm/i915: Allow NV12 with 90/270 rotation
