    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:
   30    Documentation/devicetree/bindings/regulator/regulator.txt

   32 Example:
   33 
   34         pmic@32 {
   35                 compatible = "ricoh,rn5t618";
   36                 reg = <0x32>;
   37                 interrupt-parent = <&gpio5>;
   38                 interrupts = <11 IRQ_TYPE_EDGE_FALLING>;
   39                 system-power-controller;
   40 
   41                 regulators {
   42                         DCDC1 {
   43                                 regulator-min-microvolt = <1050000>;
   44                                 regulator-max-microvolt = <1050000>;
   45                         };
   46 
   47                         DCDC2 {
   48                                 regulator-min-microvolt = <1175000>;
   49                                 regulator-max-microvolt = <1175000>;
   50                         };
   51                 };
   52         };
