My understanding is that Tomi doesn't want any new fbdev drivers, so
I'm not sure this is the right place for those patches.

My bad, I thought all auxdisplay drivers were fbdev ones, but I was
wrong, obviously. And now, I don't really know what auxdisplay is

Still, moving it to a "framework" that has been inactive for so long
(and you even mention it in your PR) doesn't seem like the right move.
