v4-v5:
- no changes

v3:
- Add Linus' R-b tag
- Remove nuvoton,interrupt-map again, to simplify the binding
- Make tuples clearer

v2:
- https://lore.kernel.org/lkml/20211207210823.1975632-7-j.neuschaefer@gmx.net/
- Move GPIO banks into subnodes
- Add /alias/gpio*

v1:
- https://lore.kernel.org/lkml/20210602120329.2444672-7-j.neuschaefer@gmx.net/
