Since the nodes are not sorted by name and since you provided
the GPIO line names, maybe it would be nicer to sort them by
gpio number for easy lookup?

Status should go last, seems like nodes following this one
haven't been updated.

You're not sorting pinctrl-N/names consistently, a recent
suggestion was to keep pinctrl-N first, as with everything
else (clocks/reg/power-domains/etc.) we do something and
then something-names.
