Description
***********



.. code-block:: none

   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.

.. tabs::

   .. group-tab:: Node specific properties

      Properties not inherited from the base binding file.

      (None)

   .. group-tab:: Deprecated node specific properties

      Deprecated properties not inherited from the base binding file.

      (None)

   .. group-tab:: 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.

                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.

Child node properties
=====================

.. list-table::
   :widths: 1 1 4
   :header-rows: 1

   * - Name
     - Type
     - Details

   * - ``regulator-min-microvolt``
     - ``int``
     - .. code-block:: none

          smallest voltage consumers may set


   * - ``regulator-max-microvolt``
     - ``int``
     - .. code-block:: none

          largest voltage consumers may set


   * - ``regulator-max-microamp``
     - ``int``
     - .. code-block:: none

          largest current consumers may set


   * - ``regulator-always-on``
     - ``boolean``
     - .. code-block:: none

          boolean, regulator should never be disabled


   * - ``regulator-boot-on``
     - ``boolean``
     - .. code-block:: none

          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-boot-off``
     - ``boolean``
     - .. code-block:: none

          Regulator should be disabled on boot.



   * - ``regulator-initial-mode``
     - ``int``
     - .. code-block:: none

          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``
     - .. code-block:: none

          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.
