drm/panel: simple: Correct G190EAN01 prepare timing

2026-05-23T11:08:48+00:00

[ Upstream commit f1080f82570b797598c1ba7e9c800ae9e94aafc6 ] The prepare timing specified by the G190EAN01 datasheet should be between 30 and 50 ms. Considering it might take some time for the LVDS encoder to enable the signal, we should only wait the min. required time in the panel driver and not the max. allowed time.

drm/panel: simple: restore connector_type fallback

2026-01-13T09:07:40+00:00

The switch from devm_kzalloc() + drm_panel_init() to devm_drm_panel_alloc() introduced a regression. Several panel descriptors do not set connector_type. For those panels, panel_simple_probe() used to compute a connector type (currently DPI as a fallback) and pass that value to drm_panel_init(). After the conversion to devm_drm_panel_alloc(), the call unconditionally used desc->connector_type instead, ignoring the computed fallback and potentially passing DRM_MODE_CONNECTOR_Unknown, which drm_panel_bridge_add() does not allow. Move the connector_type validation / fallback logic before the devm_drm_panel_alloc() call and pass the computed connector_type to devm_drm_panel_alloc(), so panels without an explicit connector_type once again get the DPI default.

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

2026-01-13T09:06:37+00:00

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.

The LD070WX3 is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED) backlight system. The matrix employs a-Si Thin Film Transistor as the active element. It is a transmissive type display operating in the normally Black mode. This TFT-LCD has 7.0 inches diagonally measured active display area with WXGA resolution (800 by 1280 pixel array). LG LD070WX3-SL01 MIPI DSI panel was treated as simple DSI panel when it is actually not and requires proper setup for correct work. Simple panel work relied on preliminary configuration done by bootloader.
