| * Ricoh RN5T567/RN5T618 PMIC |
| |
| Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which |
| integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators, |
| GPIOs, and a watchdog timer. It can be controlled through an I2C interface. |
| The RN5T618/RC5T619 provides additionally a Li-ion battery charger, |
| fuel gauge, and an ADC. |
| The RC5T619 additionnally includes USB charger detection and an RTC. |
| |
| Required properties: |
| - compatible: must be one of |
| "ricoh,rn5t567" |
| "ricoh,rn5t618" |
| "ricoh,rc5t619" |
| - reg: the I2C slave address of the device |
| |
| Sub-nodes: |
| - regulators: the node is required if the regulator functionality is |
| needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4 |
| (RN5T567/RC5T619), LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, LDO8, |
| LDO9, LDO10, LDORTC1 and LDORTC2. |
| LDO7-10 are specific to RC5T619. |
| The common bindings for each individual regulator can be found in: |
| Documentation/devicetree/bindings/regulator/regulator.txt |
| |
| Example: |
| |
| pmic@32 { |
| compatible = "ricoh,rn5t618"; |
| reg = <0x32>; |
| |
| regulators { |
| DCDC1 { |
| regulator-min-microvolt = <1050000>; |
| regulator-max-microvolt = <1050000>; |
| }; |
| |
| DCDC2 { |
| regulator-min-microvolt = <1175000>; |
| regulator-max-microvolt = <1175000>; |
| }; |
| }; |
| }; |
