Actually max77620 is not a power supply device. This patch set adds 2
features:
- Backup battery charger. The RTC in max77620 is supplied from a backup
battery and consumes 2.0uA when no other power sources are available. So
basically this is not a system battery charger, it's just for RTC.
- Low battery monitoring. This is for monitoring the system main battery
voltage, so max77620 can shutdown or reset the SoC accordingly. But I
think this doesn't conform the idea of "power supply" driver as well.
