Just "Add missing". See:

The warning is not reproduceable (as you mentioned board is not
present in mainline) thus please skip it. Instead, either describe
existing reason for this change (e.g. because bindings require it for
node of every bank of pins supporting GPIO interrupts) or include this
in series mainlining new board (where the reason will be - it will be
used by new board etc).

Best regards,
Krzysztof
