The SC27XX fuel gauge supports a low voltage alarm IRQ, which is used for more accurate battery capacity measurements with lower voltages. This was unfortunately never documented in bindings, do so now. The only in-tree user (sc2731.dtsi) has had interrupts specified since its initial fuel-gauge submission and the current kernel driver returns an error when no interrupt is specified, so also add it to the required list.
