drm/panel-simple: fix connector type for DataImage SCF0700C48GGU18 panel

2026-01-23T10:18:47+00:00

commit 6ab3d4353bf75005eaa375677c9fed31148154d6 upstream. The connector type for the DataImage SCF0700C48GGU18 panel is missing and devm_drm_panel_bridge_add() requires connector type to be set. This leads to a warning and a backtrace in the kernel log and panel does not work: " WARNING: CPU: 3 PID: 38 at drivers/gpu/drm/bridge/panel.c:379 devm_drm_of_get_bridge+0xac/0xb8 " The warning is triggered by a check for valid connector type in devm_drm_panel_bridge_add(). If there is no valid connector type set for a panel, the warning is printed and panel is not added. Fill in the missing connector type to fix the warning and make the panel operational once again.

drm/panel-simple: fix the warnings for the Evervision VGG644804

2025-06-19T13:32:18+00:00

[ Upstream commit 5dc1ea903588a73fb03b3a3e5a041a7c63a4bccd ] The panel lacked the connector type which causes a warning. Adding the connector type reveals wrong bus_flags and bits per pixel. Fix all of it.

drm/panel: Avoid warnings w/ panel-simple/panel-edp at shutdown

2024-07-22T16:00:58+00:00

At shutdown if you've got a _properly_ coded DRM modeset driver then you'll get these two warnings at shutdown time: Skipping disable of already disabled panel Skipping unprepare of already unprepared panel These warnings are ugly and sound concerning, but they're actually a sign of a properly working system. That's not great. We're not ready to get rid of the calls to drm_panel_disable() and drm_panel_unprepare() because we're not 100% convinced that all DRM modeset drivers are properly calling drm_atomic_helper_shutdown() or drm_helper_force_disable_all() at the right times. However, having the warning show up for correctly working systems is bad. As a bit of a workaround, add some "if" tests to try to avoid the warning on correctly working systems. Also add some comments and update the TODO items in the hopes that future developers won't be too confused by what's going on here.

The exynos-next pull is based on a newer -rc than drm-next. hence backmerge first to make sure the unrelated conflicts we accumulated don't end up randomly in the exynos merge pull, but are separated out. Conflicts are all benign: Adjacent changes in amdgpu and fbdev-dma code, and cherry-pick conflict in xe. Signed-off-by: Daniel Vetter
