Also the ILI9322 can actually set up gamma correction which is
very nice for professional applications. I haven't seen any way for
DRM to do gamma correction properly or any framework for it
to adjust and propagate gamma to/from userspace (seems like
another enormous task), but I am pretty sure it will be there one
of these days so I put in some comments and placeholders.
Gamma correction has been supported since approximately the dawn of
time with a 3x8-bit LUT.
But, afaik, only in the display controller side. I don't think we have
means to have any properties for the panels or bridges.
