The Maxim PMIC datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU. Without specifying the interrupt type in Devicetree, kernel might apply some fixed configuration, not necessarily working for this hardware. Additionally, the interrupt line is shared so using level sensitive interrupt is here especially important to avoid races.
