2023-08-01drm/panel: sitronix-st7789v: avoid hardcoding mode infoSebastian Reichel
Avoid hard-coding the default_mode and supply it from match data. One additional layer of abstraction has been introduced, which will be needed for specifying other panel information (e.g. bus flags) in the next steps.

2023-07-21drm: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-05-16drm/panel: Modify innolux hj110iz panel initial codeCong Yang
There is a problem of screen shake on the old panel. So increase the panel GOP component pull-down circuit size in hardware, and update the initialization code at the same time. The new initialization code mainly modifles the following. a)adjusted for GOP timing. When Display sleep in, raise all GOP signals to VGHO and then drop to GND. b)Increased the Vertical back Porch and Vertical pulse width, so need to update vsync_end and vtotal and CLK in drm_display_mode.

Commit 5dd45b66742a ("drm/panel: novatek-nt35950: Improve error handling") introduced logic to unregister DSI1 on any sort of probe failure, as that's not done automatically by kernel APIs. It did not however account for cases where only one DSI host is used. Fix that.
