drm: Deal with rotation in drm_plane_helper_check_update()
drm_plane_helper_check_update() needs to account for the plane rotation for correct clipping/scaling calculations. Do so. There was an earlier attempt [1] to add this into intel_check_primary_plane() but I requested that it'd be put into the helper instead. An updated patch never materialized AFAICS, so I went ahead and cooked one up myself. v2: Deal with new drm_plane_helper_check_update() callers [1] https://patchwork.freedesktop.org/patch/65177/ Cc: Nabendu Maiti <nabendu.bikash.maiti@intel.com> Cc: Noralf Trønnes <noralf@tronnes.org> Cc: CK Hu <ck.hu@mediatek.com> Cc: Mark Yao <mark.yao@rock-chips.com> Cc: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1466172790-10025-1-git-send-email-ville.syrjala@linux.intel.com
