MAX77620/MAX20024 are Power Management IC from the MAXIM. It supports RTC, multiple GPIOs, multiple DCDC and LDOs, watchdog, clock etc. Add MFD drier to provides common support for accessing the device; additional drivers is developed on respected subsystem in order to use the functionality of the device.
