1* ROHM BD71837 Power Management Integrated Circuit bindings
2
3BD71837MWV is a programmable Power Management IC for powering single-core,
4dual-core, and quad-core SoCs such as NXP-i.MX 8M. It is optimized for
5low BOM cost and compact solution footprint. It integrates 8 Buck
6egulators and 7 LDOs to provide all the power rails required by the SoC and
7the commonly used peripherals.

12Required properties:
13 - compatible		: Should be "rohm,bd71837".
14 - reg			: I2C slave address.
15 - interrupt-parent	: Phandle to the parent interrupt controller.
16 - interrupts		: The interrupt line the device is connected to.
17 - clocks		: The parent clock connected to PMIC. If this is missing
18			  32768 KHz clock is assumed.
19 - #clock-cells		: Should be 0.
20 - regulators:		: List of child nodes that specify the regulators.
21			  Please see ../regulator/rohm,bd71837-regulator.txt

23Optional properties:
24- clock-output-names	: Should contain name for output clock.
