Thanks!
Find some ideas for consideration below.

+Learning material +=================
Maybe 'External References'.
Agreed, I'll change it.
+Since the Linux DRM layer supports complex graphics devices, it can be quite +overwhelming for newcomers to get familiar with all the needed concepts and +learn the subsystem's internals.
It sounds a bit intimdating to me. Can we give it a positive spin?
Pekka also had reservations about this paragraph, so I think that will just drop it. The goal of having this section was to ease the learning curve but the way I worded it may reinforce the perception that DRM is hard to learn.
IMHO we could add a separate section that talks about complexity and provides guidelines about how to deal with it: trivial HW? use simple pipe; dedicated VRAM? try TTM; awkward color formats? see drm_format_helper.c
Indeed. And we can add such section as a follow-up. Maybe referring to some of the drivers in drivers/gpu/drm/tiny.
