The Ricoh RN5T567 is from the same family as the Ricoh RN5T618 is,
the differences are:
+ DCDC4/DCDC5
+ LDO7-10
+ Slightly different output voltage/currents
+ 32kHz Output
+ RTC
+ USB Charger detection

* Ricoh RN5T567/RN5T618 PMIC
-Ricoh RN5T567/RN5T618 is a power management IC family which integrates
-3 to 4 step-down DCDC converters, 7 low-dropout regulators, GPIOs and
-a watchdog timer. The RN5T618 provides additionally a Li-ion battery
-charger, fuel gauge and an ADC. It can be controlled through an I2C
-interface.
+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), LDO1, LDO2, LDO3, LDO4, LDO5, LDORTC1 and LDORTC2.

+ LDO9, LDO10, LDORTC1 and LDORTC2.
+ LDO7-10 are specific to RC5T619.
The common bindings for each individual regulator can be found in:

- Say yes here to add support for the Ricoh RN5T567 or R5T618 PMIC.
+ Say yes here to add support for the Ricoh RN5T567,
+ RN5T618, RC5T619 PMIC.
This driver provides common support for accessing the device,
additional drivers must be enabled in order to use the
functionality of the device.
