this is one of google best founds if i search for drm_fbdev_generic_setup:

https://lkml.org/lkml/2018/12/19/305

not very helpful...

so i tried kernel-doc

https://www.kernel.org/doc/html/latest/gpu/drm-kms-helpers.html?highlight=drm_fbdev_generic_setup#c.drm_fbdev_generic_setup

which is nice function-reference but i've found no generic workflow

as the posted driver is "only" a driver ported from kernel 4.4 by Alexander, i don't know if this new framework can be used and which parts need to be changed. I only try to bring his code Mainline....
Maybe CK Hu can help here because driver is originally from him and he knows internals. Or maybe you can help here?

i personally make my first steps as spare-time kernel-developer :)
