[Intel-gfx] [PATCH 3/3] drm/i915/skl: Support for 90/270 rotation
Sonika Jindal

Thu Mar 5 01:21:28 PST 2015
v2: Moving creation of property in a function, checking for 90/270
rotation simultaneously (Chris)
Letting primary plane to be positioned
v3: Adding if/else for 90/270 and rest params programming, adding check for
pixel_format, some cleanup (review comments)
v4: Adding right pixel_formats, using src_* params instead of crtc_* for offset
and size programming (Ville)
v5: Rebased on -nightly and Tvrtko's series for gtt remapping.
Signed-off-by: Sonika Jindal <sonika.jindal at intel.com>

Please note that this is on top of Tvrtko's patches for rotated gtt remapping
titled: [PATCH v2 0/8] Skylake 90/270 display rotation
