nordic,npm1100

Description

Nordic nPM1100 PMIC

The PMIC has one buck converter. It needs to be defined as a child node,
strictly following the BUCK node name. For example:

pmic {
  compatible = "nordic,npm1100";

  BUCK {
    /* all properties for BUCK */
  };
};

Note that only mode can be controlled (via GPIO pin MODE).

Properties

Top level properties

These property descriptions apply to “nordic,npm1100” 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,iset-gpios`	`phandle-array`	ISET control pin.

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,npm1100” 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
`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
`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.
`zephyr,pm-device-runtime-auto`	`boolean`	Automatically configure the device for runtime power management after the init function runs.

nordic,mode-gpios

phandle-array

MODE control pin.

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.
