nordic,npm6001-regulator

Vendor: Nordic Semiconductor

Description

Nordic nPM6001 PMIC

The PMIC has four buck converters and two LDOs. All need to be defined as
children nodes, strictly following the BUCK0..3, LDO0..1 node names. For
example:

pmic@70 {
  reg = <0x70>;
  ...
  regulators {
    compatible = "nordic,npm6001-regulator";

    BUCK0 {
      /* all properties for BUCK0 */
    };
    BUCK1 {
      /* all properties for BUCK1 */
    };
    BUCK2 {
      /* all properties for BUCK2 */
    };
    BUCK3 {
      /* all properties for BUCK3 */
    };
    LDO0 {
      /* all properties for LDO0 */
    };
    LDO1 {
      /* all properties for LDO1 */
    };
  };
};

Deprecated node specific properties

Deprecated properties not inherited from the base binding file.

(None)

Base properties

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,npm6001-regulator” compatible.

Name

Type

Details

status

string

 
indicates the operational status of a device

Legal values: 'ok', 'okay', 'disabled', 'reserved', 'fail', 'fail-sss'

See Important properties for more information.

compatible

string-array

 
compatible strings

This property is required.

See Important properties for more information.

reg

array

 
register space

See Important properties for more information.

reg-names

string-array

 
name of each register space

interrupts

array

 
interrupts for device

See Important properties for more information.

interrupts-extended

compound

 
extended interrupt specifier for device

interrupt-names

string-array

 
name of each interrupt

interrupt-parent

phandle

 
phandle to interrupt controller node

label

string

 
Human readable string describing the device (used as device_get_binding() argument)

See Important properties for more information.

This property is deprecated.

clocks

phandle-array

 
Clock gate information

clock-names

string-array

 
name of each clock

#address-cells

int

 
number of address cells in reg property

#size-cells

int

 
number of size cells in reg property

dmas

phandle-array

 
DMA channels specifiers

dma-names

string-array

 
Provided names of DMA channel specifiers

mboxes

phandle-array

 
mailbox / IPM channels specifiers

mbox-names

string-array

wakeup-source

boolean

 
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.

power-domain

phandle

 
Power domain the device belongs to.

The device will be notified when the power domain it belongs to is either
suspended or resumed.

Child node properties

Name

Type

Details

regulator-min-microvolt

int

 
smallest voltage consumers may set

regulator-max-microvolt

int

 
largest voltage consumers may set

regulator-max-microamp

int

 
largest current consumers may set

regulator-always-on

boolean

 
boolean, regulator should never be disabled

regulator-boot-on

boolean

 
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-initial-mode

int

 
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.

regulator-allowed-modes

array

 
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.
