A bit after-the-fact reasoning, but after I was made aware of an interesting
lecture by John Ousterhout I feel the best description of the descriptor
refactoring is the idea to make the GPIO API narrow and deep, make
it simple for consumers (hence <linux/gpio/consumer.h>) and handle
as much special cases (polarity inversion, open drain...) as possible
behind the scenes.
