nordic,npm1300-regulator
Vendor: Nordic Semiconductor
Note
An implementation of a driver matching this compatible is available in drivers/regulator/regulator_npm1300.c.
Description
Nordic nPM1300 PMIC
The PMIC has two buck converters and two LDOs.
The regulators need to be defined as child nodes, strictly following the
BUCK1,2 LDO1..2, node names. For
example:
pmic@6b {
reg = <0x6b>;
...
regulators {
compatible = "nordic,npm1300-regulator";
BUCK1 {
/* all properties for BUCK1 */
};
BUCK2 {
/* all properties for BUCK2 */
};
LDO1 {
/* all properties for LDO1 */
};
LDO2 {
/* all properties for LDO2 */
};
};
};
Properties
Top level properties
These property descriptions apply to “nordic,npm1300-regulator” nodes themselves. This page also describes child node properties in the following sections.
Properties not inherited from the base binding file.

|---|---|---|
|
|
List of SOC GPIOs connected to PMIC GPIOs.
Set_dvs_mode will drive these pins as follows:
DVS mode 1 will enable the first pin
DVS mode 2 will enable the second pin
DVS mode 3 will drive the first and second pins
etc.
The effect of the mode change is defined by the enable-gpios
and pwm_gpios fields for each of the regulator blocks.

Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nordic,npm1300-regulator” compatible.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.

|
|
bootloader/firmware enabled regulator.
It's expected that this regulator was left on by the bootloader.
If the bootloader didn't leave it on then OS should turn it on
at boot but shouldn't prevent it from being turned off later.
This property is intended to only be used for regulators where
software cannot read the state of the regulator.
|
|
|
Regulator should be disabled on boot.
|
|
|
Initial operating mode. The set of possible operating modes depends on the
capabilities of every hardware so each device binding documentation
explains which values the regulator supports.
|
|
|
List of operating modes that software is allowed to configure for the
regulator at run-time. Elements may be specified in any order. The set of
possible operating modes depends on the capabilities of every hardware so
each device binding document explains which values the regulator supports.
