This patch will have to be rebased to apply and compile after the release
of kernel v4.5-rc1, as we have too much lined up right now, I see no
big problems
with it but here are some more minor comments.

We are getting rid of this design pattern, check the gpiochip_get_data()
function that will be introduced in v4.5-rc1 and patches I merge to all
other drivers.

No device tree probing? Which platform uses this?
I was expecting an .of_match_table()  in .driver.
