Sashiko had some feedback on the interrupt - if you are respinning for
other reasons it might be good to add a comment in the dt-binding about
it being an edge interrupt. From a quick look at the datasheet a level
interrupt would not make much sense.

Other than that, looks good to me.  You've had a lot of review from
others though so I'll leave it on list for a little while in case
any one wants to take a final look and perhaps give tags.

Thanks,
