But here I worry about breaking in-transition systems, e.g. defining part of the peripherals through DT but adding a GPIO device with AUXDATA, setting up base that way.

Not that it should stay that way for sure, but it does need some consideration...

Could we add a flag that the boards can use to override this behaviour?
