mfd: rn5t618: Add Ricoh RC5T619 PMIC support 



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.

   (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:
