* ROHM BD9571MWV Power Management Integrated Circuit (PMIC) bindings
|
|
|
|
Required properties:
|
|
- compatible : Should be "rohm,bd9571mwv".
|
|
- reg : I2C slave address.
|
|
- interrupt-parent : Phandle to the parent interrupt controller.
|
|
- 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.
|
|
|
|
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>;
|
|
|
|
regulators {
|
|
dvfs: dvfs {
|
|
regulator-name = "dvfs";
|
|
regulator-min-microvolt = <750000>;
|
|
regulator-max-microvolt = <1030000>;
|
|
regulator-boot-on;
|
|
regulator-always-on;
|
|
};
|
|
};
|

};
