drm/panel: himax-hx83102: Adjust power and gamma to optimize brightness

2024-11-01T01:02:27+00:00

[ Upstream commit fcf38bc321fbc87dfcd829f42e64e541f17599f7 ] The current panel brightness is only 360 nit. Adjust the power and gamma to optimize the panel brightness. The brightness after adjustment is 390 nit.

drm/panel: sharp-lq101r1sx01: Fixed reversed "if" in remove

2024-07-09T15:24:05+00:00

Commit d7d473d8464e ("drm/panel: sharp-lq101r1sx01: Don't call disable at shutdown/remove") had a subtle bug. We should be calling sharp_panel_del() when the "sharp" variable is non-NULL, not when it's NULL. Fix.

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

drm/panel: jd9365da: Add the function of adjusting orientation

This driver does not have the function to adjust the orientation, so this function is added.

drm/panel: jd9365da: Support for kd101ne3-40ti MIPI-DSI panel

2024-06-28T08:33:24+00:00

The K&d kd101ne3-40ti is a 10.1" WXGA TFT-LCD panel, use jd9365da controller,which fits in nicely with the existing panel-jadard-jd9365da-h3 driver.Hence,we add a new compatible with panel specific config. Although they have the same control IC, the two panels are different, and the timing will be slightly different, so we added some variables in struct jadard_panel_desc to control the timing.

drm/panel: jd9365da: Modify the method of sending commands

2024-06-28T08:33:22+00:00

Currently, the init_code of the jd9365da driver is placed in the enable() function and sent, but this seems to take a long time. It takes 17ms to send each instruction (an init code consists of about 200 instructions), so it takes about 3.5s to send the init_code. So we moved the sending of the inti_code to the prepare() function, and each instruction seemed to take only 25μs. We checked the DSI host and found that the difference in command sending time is caused by the different modes of the DSI host in prepare() and enable() functions. Our DSI Host only supports sending cmd in LP mode, The prepare() function can directly send init_code (LP->cmd) in LP mode, but the enable() function is in HS mode and needs to switch to LP mode before sending init code (HS->LP->cmd->HS). Therefore, it takes longer to send the command.
