I agree. But I would like to avoid specifying 44 "interrupts" in DT files if they are known a priory in driver for specific chip. Only drawback that I could see is that it will be little odd for client drivers, which are using SPMI PMIC pinctrl driver, to specify 4 parameters required by interrupts property.
