Regmap irq implements the generic interrupt service routine which is common for most of devices. Some devices, like MAX77620, MAX20024 needs the special handling before and after servicing the interrupt as generic. For the example, MAX77620 programming guidelines for interrupt servicing says: 1. When interrupt occurs from PMIC, mask the PMIC interrupt by setting GLBLM. 2. Read IRQTOP and service the interrupt accordingly. 3. Once all interrupts has been checked and serviced, the interrupt service routine un-masks the hardware interrupt line by clearing GLBLM. The step (2) is implemented in regmap irq as generic routine. For step (1) and (3), add callbacks from regmap irq to client driver to handle chip specific configurations.
