sprdfb_check_var() has two problems:
|
||||
I) it is not buffering-aware, which all Spreadtrum devices use;
|
||||
II) it checks values that are already in yres_virtual, not those that we
|
||||
are trying to overwrite.
|
||||
Those problems stop X11 and charging-sdl from working properly.
|
||||
X11 error:
|
||||
(EE) FBDEV(0): FBIOPUT_VSCREENINFO: Invalid argument
|
||||
This patch fixes first problem, however, the correct way is fixing
|
||||
the second one, as this might have less side effects.

By default, color channels on Spreadtrum devices are swapped. This patch makes kernel use BGR565, which has normal color channels.
