description: |
This is a part of device tree bindings for Maxim MAX14577/MAX77836 MicroUSB
Integrated Circuit (MUIC).
The Maxim MAX14577 is a MicroUSB and Companion Power Management IC which
includes voltage safeout regulators, charger and MicroUSB management IC.
The Maxim MAX77836 is a MicroUSB and Companion Power Management IC which
includes voltage safeout and LDO regulators, charger, fuel-gauge and MicroUSB
management IC.
