1* ROHM BD9571MWV Power Management Integrated Circuit (PMIC) bindings
2
3Required properties:
4 - compatible		: Should be "rohm,bd9571mwv".
5 - reg			: I2C slave address.
6 - interrupts		: The interrupt line the device is connected to.
7 - interrupt-controller	: Marks the device node as an interrupt controller.
8 - #interrupt-cells	: The number of cells to describe an IRQ, should be 2.
9			    The first cell is the IRQ number.
10			    The second cell is the flags, encoded as trigger
11			    masks from ../interrupt-controller/interrupts.txt.
12 - gpio-controller      : Marks the device node as a GPIO Controller.
13 - #gpio-cells          : Should be two.  The first cell is the pin number and
14                            the second cell is used to specify flags.
15                            See ../gpio/gpio.txt for more information.
16 - regulators:          : List of child nodes that specify the regulator
17                            initialization data. Child nodes must be named
18                            after their hardware counterparts:
19			     - vd09
20			     - vd18
21			     - vd25
22			     - vd33
23			     - dvfs
24			    Each child node is defined using the standard
25			    binding for regulators.
26
27Optional properties:
28  - rohm,ddr-backup-power : Value to use for DDR-Backup Power (default 0).
29			    This is a bitmask that specifies which DDR power
30			    rails need to be kept powered when backup mode is
31			    entered, for system suspend:
32			      - bit 0: DDR0
33			      - bit 1: DDR1
34			      - bit 2: DDR0C
35			      - bit 3: DDR1C
36			    These bits match the KEEPON_DDR* bits in the
37			    documentation for the "BKUP Mode Cnt" register.
38  - rohm,rstbmode-level: The RSTB signal is configured for level mode, to
39			 accommodate a toggle power switch (the RSTBMODE pin is
40			 strapped low).
41  - rohm,rstbmode-pulse: The RSTB signal is configured for pulse mode, to
42			 accommodate a momentary power switch (the RSTBMODE pin
43			 is strapped high).
44			 The two properties above are mutually exclusive.
