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 */
    };
  };
};

Properties

Top level properties

These property descriptions apply to “nordic,npm6001-regulator” nodes themselves. This page also describes child node properties in the following sections.

Properties not inherited from the base binding file.

Name

Type

Details

nordic,ready-high-drive

boolean

Set drive strength to high for READY pin.

nordic,nint-high-drive

boolean

Set drive strength to high for NINT pin.

nordic,sda-high-drive

boolean

Set drive strength to high for SDA pin.

nordic,buck-mode0-input-type

string

Input type for BUCK_MODE0 pin. Defaults IC boot-time value.

Default value: schmitt

Legal values: 'schmitt', 'cmos'

nordic,buck-mode0-pull-down

boolean

Enable pull-down resistor for BUCK_MODE0 pin.

nordic,buck-mode1-input-type

string

Input type for BUCK_MODE1 pin. Defaults IC boot-time value.

Default value: schmitt

Legal values: 'schmitt', 'cmos'

nordic,buck-mode1-pull-down

boolean

Enable pull-down resistor for BUCK_MODE1 pin.

nordic,buck-mode2-input-type

string

Input type for BUCK_MODE2 pin. Defaults IC boot-time value.

Default value: schmitt

Legal values: 'schmitt', 'cmos'

nordic,buck-mode2-pull-down

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.
