Hi Robert,

This patch adds device tree node for IRQ used by max8997.


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.
