Thank you for suggesting this.  Huan Feng originally wrote the driver.
Emil and I have made some changes to reorganize and clean it up for
submission.

Do you think all three of us should list Co-developed-by: for our names
in addition to the SOB?

Michael Walle asked about this yesterday and it was my first time
looking at regmap and gpio-regmap.  I've been reading the code and it
does look like I should try convert this driver over to using
gpio-regmap.

The open question in my mind is how to handle the interrupt type (edge
trigged on positive or negative, level triggered on high or low).
Hopefully I can find some other examples that can help me think about
how to do that correctly.

Thanks,
Drew
