Subject: [PATCH v8 06/12] pinctrl: single: create new gpio function range

Minor typo above: s/invokes/invoke/

I think the second gpio-ranges above should be really
pinctr-single,gpio-range instead of gpio-ranges?

Other than that looks OK to me. Assuming the other related GPIO patches
are fine and don't cause changes to this:
