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