The Maxim 17042-family of fuel gauges are often embedded in other Maxim chips, e.g. in Maxim 77693 which is a companion power management IC. In such designs there might be actually two interrupts: - INTB signaling change from charger, flash or MUIC, - ALERT signaling change from fuel gauge. Describe the interrupt in bindings to make it clear it is about the fuel gauge ALERT interrupt, not the INT.
