From b882872e4391bf38d8cb7fb2544d6941f297b57d Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Tue, 1 Feb 2022 12:20:20 +0000 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.
