2026-03-04drm/panel: Fix a possible null-pointer dereference in jdi_panel_dsi_remove()Tuo Li1-1/+3
[ Upstream commit 95eed73b871111123a8b1d31cb1fce7e902e49ea ] In jdi_panel_dsi_remove(), jdi is explicitly checked, indicating that it may be NULL: if (!jdi) mipi_dsi_detach(dsi); However, when jdi is NULL, the function does not return and continues by calling jdi_panel_disable(): err = jdi_panel_disable(&jdi->base); Inside jdi_panel_disable(), jdi is dereferenced unconditionally, which can lead to a NULL-pointer dereference: struct jdi_panel *jdi = to_panel_jdi(panel); backlight_disable(jdi->backlight); To prevent such a potential NULL-pointer dereference, return early from jdi_panel_dsi_remove() when jdi is NULL.

2026-01-23drm/panel-simple: fix connector type for DataImage SCF0700C48GGU18 panelMarek Vasut1-0/+1
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.

We'll still go a little extra conservative and allow `hpd_absent` of 200 instead of 100 because that won't add any real-world delay in most cases. We'll associate the string from the EDID ("116KHD024006") with this panel. Given that the ID is the suspicious value of 0x0004 it seems likely that Starry doesn't always update their IDs but the string will still work to differentiate if we ever need to in the future.

commit 095c8e61f4c71cd4630ee11a82e82cc341b38464 upstream. commit a8972d5a49b4 ("drm: panel: jd9365da-h3: fix reset signal polarity") fixed reset signal polarity in jadard_dsi_probe() and jadard_prepare(). It was not done in jadard_unprepare() because of an incorrect assumption about reset line handling in power off mode. After looking into the datasheet, it now appears that before disabling regulators, the reset line is deasserted first, and if reset_before_power_off_vcioo is true, then the reset line is asserted.

commit a8972d5a49b408248294b5ecbdd0a085e4726349 upstream. In jadard_prepare() a reset pulse is generated with the following statements (delays ommited for clarity): gpiod_set_value(jadard->reset, 1); --> Deassert reset gpiod_set_value(jadard->reset, 0); --> Assert reset for 10ms gpiod_set_value(jadard->reset, 1); --> Deassert reset However, specifying second argument of "0" to gpiod_set_value() means to deassert the GPIO, and "1" means to assert it. If the reset signal is defined as GPIO_ACTIVE_LOW in the DTS, the above statements will incorrectly generate the reset pulse (inverted) and leave it asserted (LOW) at the end of jadard_prepare(). Fix reset behavior by inverting gpiod_set_value() second argument in jadard_prepare(). Also modify second argument to devm_gpiod_get() in jadard_dsi_probe() to assert the reset when probing. Do not modify it in jadard_unprepare() as it is already properly asserted with "1", which seems to be the intended behavior.

2024-08-27Revert "drm/panel-edp: Add SDC ATNA45AF01"Stephan Gerhold1-2/+0
This reverts commit 8ebb1fc2e69ab8b89a425e402c7bd85e053b7b01. The panel should be handled through the samsung-atna33xc20 driver for correct power up timings. Otherwise the backlight does not work correctly. We have existing users of this panel through the generic "edp-panel" compatible (e.g. the Qualcomm X1E80100 CRD), but the screen works only partially in that configuration: It works after boot but once the screen gets disabled it does not turn on again until after reboot. It behaves the same way with the default "conservative" timings, so we might as well drop the configuration from the panel-edp driver. That way, users with old DTBs will get a warning and can move to the new driver.

Move the "exit sleep mode" and "set display on" command from enable() to init() function. As mentioned in the patch: https://lore.kernel.org/all/20240624141926.5250-2-lvzhaoxiong@huaqin.corp-partner.google.com/ The Mediatek Soc DSI host has different modes in prepare() and enable() functions, prepare() is in LP mode and enable() is in HS mode. Since the "exit sleep mode" and "set display on" command must also be sent in LP mode, so we also move "exit sleep mode" and "set display on" command to the init() function. We have no other actions in the enable() function after moves "exit sleep mode" and "set display on", and we checked the call of the enable() function during the "startup" process. It seems that only one judgment was made in drm_panel_enabel(). If the panel does not define enable(), the judgment will skip the enable() and continue execution. This does not seem to have any other effect, and we found that some drivers also seem to have no enable() function added, for example: panel-asus-z00t-tm5p5-n35596 / panel-boe-himax8279d... In addition, we briefly tested the kingdisplay_kd101ne3 panel and melfas_lmfbx101117480 panel, and it seems that there is no garbage on the panel, so we delete enable() function. After moving the "exit sleep mode" and "set display on" command to the init() function, we no longer need additional delay judgment, so we delete variables "exit_sleep_to_display_on_delay_ms" and "display_on_delay_ms".
