* ROHM BD9571MWV/BD9574MWF Power Management Integrated Circuit (PMIC) bindings

Required properties:

 - 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.

 - #interrupt-cells	: The number of cells to describe an IRQ, should be 2.

			    The first cell is the IRQ number.

			    The second cell is the flags, encoded as trigger

			    masks from ../interrupt-controller/interrupts.txt.

 - gpio-controller      : Marks the device node as a GPIO Controller.

 - #gpio-cells          : Should be two.  The first cell is the pin number and

                            the second cell is used to specify flags.

                            See ../gpio/gpio.txt for more information.

 - regulators:          : List of child nodes that specify the regulator

                            initialization data. Child nodes must be named

                            after their hardware counterparts:

			     - vd09

			     - vd18

			     - vd25

			     - vd33

			     - dvfs

			    Each child node is defined using the standard

			    binding for regulators.

Optional properties:

  - rohm,ddr-backup-power : Value to use for DDR-Backup Power (default 0).

			    This is a bitmask that specifies which DDR power

			    rails need to be kept powered when backup mode is

			    entered, for system suspend:

			      - bit 0: DDR0

			      - bit 1: DDR1

			      - bit 2: DDR0C

			      - bit 3: DDR1C

			    These bits match the KEEPON_DDR* bits in the

			    documentation for the "BKUP Mode Cnt" register.

  - rohm,rstbmode-level: The RSTB signal is configured for level mode, to

			 accommodate a toggle power switch (the RSTBMODE pin is

			 strapped low).

  - rohm,rstbmode-pulse: The RSTB signal is configured for pulse mode, to

			 accommodate a momentary power switch (the RSTBMODE pin

			 is strapped high).

			 The two properties above are mutually exclusive.

Example:

	pmic: pmic@30 {

		compatible = "rohm,bd9571mwv";

		reg = <0x30>;

		interrupt-parent = <&gpio2>;

		interrupts = <0 IRQ_TYPE_LEVEL_LOW>;

		interrupt-controller;

		#interrupt-cells = <2>;

		gpio-controller;

		#gpio-cells = <2>;

		rohm,ddr-backup-power = <0xf>;

		rohm,rstbmode-pulse;

		regulators {

			dvfs: dvfs {

				regulator-name = "dvfs";

				regulator-min-microvolt = <750000>;

				regulator-max-microvolt = <1030000>;

				regulator-boot-on;

				regulator-always-on;

			};

		};
