A lot of trouble to access a single GPIO pin (I guess _N means "active low"?)

Is this line used for something especially important? Would be nice to
include in some commit message like patch 1/5 why we invest so much
energy to accessing this pin.

Just curious. If you're just aiming for feature completion, that is a good
reason as well :D
