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.

[ Upstream commit c222177d7c7e1b2e0433d9e47ec2da7015345d50 ] The DSI link must be powered up to let panel driver to talk to the panel during prepare() callback execution. Set the prepare_prev_first flag to guarantee this.

drm/panel: boe-tv101wum-nl6: restore MODE_LPM after sending disable cmds

2026-05-17T15:16:32+00:00

commit 570cf799e87ae805eacfab3b4ba66676b5fccdb6 upstream. When preparing the panel, it seems that it always expects commands to be transferred in LP mode. However, the disable function removes the MIPI_DSI_MODE_LPM flag, and no other function re-adds it. As the unprepare function contains no DSI commands, re-adding the flag just after disabling the panel should be safe. Add the code re-adding the flag after the two commands for disabling the panel are sent. This fixes error messages shown in kernel log when unblanking on mt8183-kukui-kodama-sku32 device.

For clang, -Wextra in drivers/gpu/drm/Makefile turns it back but GCC respects turning it off earlier in the command line. Of all the duplicate fields in the initializer, only nfl_bpg_offset is a different value. Clear up the duplicate initializers, keeping the 'false' value for .vbr_enable, as it is bool, and the second value for .nfl_bpg_offset, assuming it is the correct one since it was the one tested in the original change.

drm/panel: jd9365da: Support for Anbernic RG-DS Panel

2026-01-20T10:13:15+00:00

Add support for both panels used in the Anbernic RG-DS. These panels are physically identical and differ only with a single instruction in the init sequence. The init sequence commands suggest it uses an identical controller as the jd9365da. Additionally, allow specifying per-panel dsi->mode_flags that can override the default values.
