From: Ville Syrjälä <ville.syrjala@linux.intel.com>
The sprite planes (in fact all display planes starting from gen4)
support 180 degree rotation. Add the relevant low level bits to the
sprite code to make use of that feature.
The upper layers are not yet plugged in.
v2: HSW handles the rotated buffer offset automagically
v3: BDW also handles the rotated buffer offset automagically
Testcase: igt/kms_rotation_crc

Propagate the error from intel_update_plane() up through
intel_plane_restore() to the caller. This will be used for
rollback purposes when setting properties fails.

Primary planes support 180 degree rotation. Expose the feature
through rotation drm property.
v2: Calculating linear/tiled offsets based on pipe source width and
height. Added 180 degree rotation support in ironlake_update_plane.
v3: Checking if CRTC is active before issueing update_plane. Added
wait for vblank to make sure we dont overtake page flips. Disabling
FBC since it does not work with rotated planes.
v4: Updated rotation checks for pending flips, fbc disable. Creating
rotation property only for Gen4 onwards. Property resetting as part
of lastclose.
v5: Resetting property in i915_driver_lastclose properly for planes
and crtcs. Fixed linear offset calculation that was off by 1 w.r.t
width in i9xx_update_plane and ironlake_update_plane. Removed tab
based indentation and unnecessary braces in intel_crtc_set_property
and intel_update_fbc. FBC and flip related checks should be done only
for valid crtcs.
v6: Minor nits in FBC disable checks for comments in intel_crtc_set_property
and positioning the disable code in intel_update_fbc.
v7: In case rotation property on inactive crtc is updated, we return
successfully printing debug log as crtc is inactive and only property change
is preserved.
v8: update_plane is changed to update_primary_plane, crtc->fb is changed to
crtc->primary->fb and return value of update_primary_plane is ignored.
v9: added rotation property to primary plane instead of crtc. Removing reset
of rotation property from lastclose. rotation_property is moved to
drm_mode_config, so drm layer will take care of resetting. Adding updation of
fbc when rotation is set to 0. Allowing rotation only if value is
different than old one.

The series looks good to me.

You've managed to cc exactly the wrong set of patches to dri-devel, namely
the i915 specific ones. You should have cc'ed just the ones touching core
drm (more if you feel like). Can you please fix that by resending?
I've pulled them into dinq for now meanwhile.
Thanks, Daniel
