From: Sonika Jindal <sonika.jindal@intel.com>

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_plane,so
drm layer will take care of resetting.

Testcase: igt/kms_rotation_crc

Hum, I don't think this was supposed to be removed?

Here and elsewhere, you're adding dev_priv to remove it in the next
patch. A left over from putting the rotation property in drm_plane.
