Properties

.. tabs::

   .. group-tab:: Node specific properties

      Properties not inherited from the base binding file.

      .. 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-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-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.



         * - ``raspberrypi,brown-out-detection``
           - ``boolean``
           - .. code-block:: none

                Enable brown-out detection


         * - ``raspberrypi,brown-out-threshold``
           - ``int``
           - .. code-block:: none

                Reset if the core voltage drops below this threshold for a particular time
                (determined by the 'brown-out detection assertion delay').



             Default value: ``860000``

             Legal values: ``473000``, ``516000``, ``559000``, ``602000``, ``645000``, ``688000``, ``731000``, ``774000``, ``817000``, ``860000``, ``903000``, ``946000``, ``989000``, ``1032000``, ``1075000``, ``1118000``

      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 "raspberrypi,core-supply-regulator" compatible.

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

         * - Name

           - .. code-block:: none

                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.
