that suggests that you have several different drivers.
each under their own tree to get the same "place"
as the ones already there, that build cleanly,
use the subsystem support, and work.

the path of least resistance might be to just put it in staging.
Once its there and building, thats a milestone.
then when it "works" there, thats clearly another.
then maybe break it up into several ko's if feedback says.
