Generally, this patch does not add just a node, but rather "IRQ line
specification for the MAX8997 PMIC chip and necessary pinctrl group to
configure pull-up and driver strength of the pin".
Also it would be nice to mention a reason for this change, e.g. what can
be achieved after applying this patch.
Otherwise looks good.
