   1 * Ricoh RN5T618 PMIC
   2
   3 Ricoh RN5T618 is a power management IC which integrates 3 step-down
   4 DCDC converters, 7 low-dropout regulators, a Li-ion battery charger,
   5 fuel gauge, ADC, GPIOs and a watchdog timer. It can be controlled
   6 through a I2C interface.
   7
   8 Required properties:
   9  - compatible: should be "ricoh,rn5t618"
  10  - reg: the I2C slave address of the device
  11
  12 Sub-nodes:
  13  - regulators: the node is required if the regulator functionality is
  14    needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, LDO1,
  15    LDO2, LDO3, LDO4, LDO5, LDORTC1 and LDORTC2.
  16    The common bindings for each individual regulator can be found in:

  24
  25                 regulators {
  26                         DCDC1 {
  27                                 regulator-min-microvolt = <1050000>;
  28                                 regulator-max-microvolt = <1050000>;
  29                         };
