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