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.
