Haven't reviewed the actual code but at an interface level it seems
sane.  It'd be nice to actually implement a driver for some nutbars SoC
and make sure it all shakes out but in the first instance I can't see
any problems.

Leaving it orthogonal to gpio is a great move conceptually and if it does
need to be tied back to the gpio_request() interface later then, well,
we'll cross that bridge when we come to it.

Thanks for your work in this area, looking good.
