   4 Subject: [PATCH 1051/1085] drm/panel: Add and initialise an orientation field
   5  to drm_panel from OF
   6
   7 "rotation" is listed as a standard property of panels in panel-common.yaml,
   8 therefore it would be logical to process that from within the core
   9 code should a panel driver not implement the get_orientation hook.
  10
  11 Call of_drm_get_panel_orientation from
  12 drm_connector_set_orientation_from_panel to get that information.
  13
  14 This removes the need for any boiler-plate in panel drivers for calling
  15 drm_connector_set_orientation_from_panel or
  16 drm_connector_set_panel_orientation.
