* ROHM BD9571MWV Power Management Integrated Circuit (PMIC) bindings
* ROHM BD9571MWV/BD9574MWF Power Management Integrated Circuit (PMIC) bindings
Required properties:
- compatible : Should be "rohm,bd9571mwv".
- compatible : Should be "rohm,bd9571mwv" or "rohm,bd9574mwf".
- reg : I2C slave address.
- interrupts : The interrupt line the device is connected to.
- interrupt-controller : Marks the device node as an interrupt controller.
