nordic,npm2100-regulator

Note

An implementation of a driver matching this compatible is available in drivers/regulator/regulator_npm2100.c.

Description

Nordic nPM2100 PMIC

The PMIC has one boost converter and one LDO/LDSW.
The regulators need to be defined as child nodes,
strictly following the BOOST, LDOSW node names.
For example:

pmic@74 {
  reg = <0x74>;
  ...
  regulators {
    compatible = "nordic,npm2100-regulator";

    BOOST {
      /* all properties for BOOST */
    };
    LDOSW {
      /* all properties for LDOSW */
    };
  };
};

These property descriptions apply to “nordic,npm2100-regulator” nodes themselves. This page also describes child node properties in the following sections.

Properties not inherited from the base binding file.

dvs-gpios

phandle-array

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
The effect of the mode change is defined by the mode-gpios
fields for each of the regulator blocks.

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,npm2100-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`	No description provided for this label See Important properties for more information.
`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
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`power-domains`	`phandle-array`	Power domain specifiers
`power-domain-names`	`string-array`	Provided names of power domain specifiers
`#power-domain-cells`	`int`	Number of cells in power-domains property
`zephyr,deferred-init`	`boolean`	Do not initialize device automatically on boot. Device should be manually initialized using device_init().
`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.
`zephyr,pm-device-runtime-auto`	`boolean`	Automatically configure the device for runtime power management after the init function runs.
`zephyr,disabling-power-states`	`phandles`	List of power states that will disable this device power.

Child node properties

Name	Type	Details
`mode-gpios`	`phandle-array`	Regulator mode controlled by specified regulator GPIO pin.
`ldosw-wd-reset`	`boolean`	LDOSW turned off by watchdog reset.
`dps-timer-us`	`int`	Interval between DPS refresh cycles in microseconds. Legal values: `100`, `200`, `400`, `800`
`dps-pulse-limit`	`int`	DPS coil pulse limit per refresh cycle.
`regulator-init-microvolt`	`int`	Voltage set during initialisation
`regulator-min-microvolt`	`int`	smallest voltage consumers may set
`regulator-max-microvolt`	`int`	largest voltage consumers may set
`regulator-init-microamp`	`int`	Current set during initialisation
`regulator-min-microamp`	`int`	smallest current 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.
