-* 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;
- };
- };
- };

Convert the ROHM BD9571MWV/BD9574MWF Power Management Integrated Circuit (PMIC) Device Tree binding documentation to json-schema. Make the "regulators" subnode optional, as not all users describe the regulators.
