   1 * Ricoh RN5T567/RN5T618 PMIC
   2
   3 Ricoh RN5T567/RN5T618 is a power management IC family which integrates
   4 3 to 4 step-down DCDC converters, 7 low-dropout regulators, GPIOs and
   5 a watchdog timer. The RN5T618 provides additionally a Li-ion battery
   6 charger, fuel gauge and an ADC. It can be controlled through an I2C
   7 interface.

   9 Required properties:
  10  - compatible: must be one of
  11                 "ricoh,rn5t567"
  12                 "ricoh,rn5t618"
  13  - reg: the I2C slave address of the device
  14
  15 Sub-nodes:
  16  - regulators: the node is required if the regulator functionality is
  17    needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4
  18    (RN5T567), LDO1, LDO2, LDO3, LDO4, LDO5, LDORTC1 and LDORTC2.
  19    The common bindings for each individual regulator can be found in:
