* STMicroelectronics STPMIC1 Power Management IC

Required properties:
- compatible:		: "st,stpmic1"
- reg:			: The I2C slave address for the STPMIC1 chip.
- interrupts:		: The interrupt line the device is connected to.
- #interrupt-cells:	: Should be 1.
- interrupt-controller:	: Marks the device node as an interrupt controller.
			    Interrupt numbers are defined at
			    dt-bindings/mfd/st,stpmic1.h.

STPMIC1 consists in a varied group of sub-devices.
Each sub-device binding is be described in own documentation file.

Device			 Description
------			------------
st,stpmic1-onkey	: Power on key, see ../input/st,stpmic1-onkey.txt
st,stpmic1-regulators	: Regulators, see ../regulator/st,stpmic1-regulator.txt
st,stpmic1-wdt		: Watchdog, see ../watchdog/st,stpmic1-wdt.txt
