Patch applied.

It seems this is one of those drivers that could also implement
.set_single_ended() and support native open drain.

Either it can do so by poking that pin config directly from the
gpiochip callback or by figuring out how to interface with the
pin config backend and do it genercially... I've been thinking a
bit about that.
