TODO:

	- complete rewrite:

	  1. The underlying fbdev drivers need to be converted into drm kernel

	     modesetting drivers.

	  2. The dcon low-power display mode can then be integrated using the

	     drm damage tracking and self-refresh helpers.

	  This bolted-on self-refresh support that digs around in fbdev

	  internals, but isn't properly integrated, is not the correct solution.

	- see if vx855 gpio API can be made similar enough to cs5535 so we can

	  share more code

	- convert all uses of the old GPIO API from <linux/gpio.h> to the
