I'm happy to point you at such docs as there are and answer as many questions on this. It's not ideal, but it's what we have. We've made the decision to use the FDT standard, which forces us down certain paths. When I wrote the pinmux / pinctl stuff for Atmel, it took me about two days to complete, most of that was understanding what needed to be done. Part of the problem is that the original RPi port pre-dated a lot of these efforts, and the followon ports have been incremental efforts to add in missing bits incrementally w/o regard to modernizing, but no one has gone back and put in the effort to modernize. You're running up against that issue right now, if you want to help revitalize the rpi port. Warner
