-* 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
