   1 * Ricoh RN5T567/RN5T618 PMIC
   2
   3 Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which
   4 integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators,
   5 GPIOs, and a watchdog timer. It can be controlled through an I2C interface.
   6 The RN5T618/RC5T619 provides additionally a Li-ion battery charger,
   7 fuel gauge, and an ADC.
   8 The RC5T619 additionnally includes USB charger detection and an RTC.

  10 Required properties:
  11  - compatible: must be one of
  12                 "ricoh,rn5t567"
  13                 "ricoh,rn5t618"
  14                 "ricoh,rc5t619"
  15  - reg: the I2C slave address of the device
  16
  17 Optional properties:
  18  - interrupts: interrupt mapping for IRQ
  19    See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
  20  - system-power-controller:
  21    See Documentation/devicetree/bindings/power/power-controller.txt
  22
  23 Sub-nodes:
  24  - regulators: the node is required if the regulator functionality is
  25    needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4
  26    (RN5T567/RC5T619), LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, LDO8,
  27    LDO9, LDO10, LDORTC1 and LDORTC2.
  28    LDO7-10 are specific to RC5T619.
  29    The common bindings for each individual regulator can be found in:
