this driver is pretty horrible from a design pov, and needs a complete overhaul. Concrete thing that annoys me is that it looks at registered_fb, which is an internal thing to fbmem.c and fbcon.c. And ofc it gets the lifetime rules all wrong (it should at least use get/put_fb_info). Looking at the history, there's been an attempt at dropping this from staging in 2016, but that had to be reverted. Since then not real effort except the usual stream of trivial patches, and fbdev has been formally closed for any new hw support. Time to try again and drop this?

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
|
|
GPIO descriptor API in <linux/gpio/consumer.h> and look up GPIO
|
|
lines from device tree, ACPI or board files, board files should
|
|
use <linux/gpio/machine.h>
|
|
- allow simultaneous XO-1 and XO-1.5 support
