.. code-block:: none

   NXP S32K3xx Power Management Controller (PMC)

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

         * - ``lm-reg``
           - ``boolean``
           - .. code-block:: none

                Enables the Last Mile regulator, which regulates an external 1.5V
                voltage on V15 down to the core and logic supply (V11 power domain),
                which is typically 1.1V.
                When enabling PLL as system clock, the PMC Last Mile regulator should
                be enabled.



         * - ``lm-reg-auto``
           - ``boolean``
           - .. code-block:: none

                Enables to turn over automatically from Boot Regulator Mode to Last Mile
                regulator mode and vice versa, depending on the V15 voltage status.
                When configuring system clocks higher than FIRC clock frequency,
                lm-reg should be also enabled.



         * - ``lm-reg-base-control``
           - ``boolean``
           - .. code-block:: none

                Enable this if an external BJT between VDD_HV_A and V15 is used on the
                PCB. The base of this BJT must be connected to the VRC_CTRL pin and is
                controlled by the PMC to regulate a voltage of 1.5V on V15 pin.





   .. 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 "nxp,s32k3-pmc" compatible.

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

         * - Name
           - Type
           - Details

         * - ``reg``
           - ``array``
           - .. code-block:: none

                Information used to address the device. The value is specific to
                the device (i.e. is different depending on the compatible
                property).

                The "reg" property is typically a sequence of (address, length) pairs.
                Each pair is called a "register block". Values are
                conventionally written in hex.

                For details, see "2.3.6 reg" in Devicetree Specification v0.4.



             This property is **required**.

             See :ref:`zephyr:dt-important-props` for more information.

         * - ``status``
           - ``string``
           - .. code-block:: none

                Indicates the operational status of the hardware or other
                resource that the node represents. In particular:

                  - "okay" means the resource is operational and, for example,
                    can be used by device drivers
                  - "disabled" means the resource is not operational and the system
                    should treat it as if it is not present

                For details, see "2.3.4 status" in Devicetree Specification v0.4.



             Legal values: ``'ok'``, ``'okay'``, ``'disabled'``, ``'reserved'``, ``'fail'``, ``'fail-sss'``

             See :ref:`zephyr:dt-important-props` for more information.

         * - ``compatible``
           - ``string-array``
           - .. code-block:: none

                This property is a list of strings that essentially define what
                type of hardware or other resource this devicetree node
                represents. Each device driver checks for specific compatible
                property values to find the devicetree nodes that represent
                resources that the driver should manage.

                The recommended format is "vendor,device", The "vendor" part is
                an abbreviated name of the vendor. The "device" is usually from
                the datasheet.

                The compatible property can have multiple values, ordered from
                most- to least-specific. Having additional values is useful when the
                device is a specific instance of a more general family, to allow the
                system to match the most specific driver available.

                For details, see "2.3.1 compatible" in Devicetree Specification v0.4.



             This property is **required**.

             See :ref:`zephyr:dt-important-props` for more information.

         * - ``reg-names``
           - ``string-array``
           - .. code-block:: none

                Optional names given to each register block in the "reg" property.
                For example:

                  / {
                       soc {
                           #address-cells = <1>;
                           #size-cells = <1>;

                           uart@1000 {
                               reg = <0x1000 0x2000>, <0x3000 0x4000>;
                               reg-names = "foo", "bar";
                           };
                       };
                  };

                The uart@1000 node has two register blocks:

                  - one with base address 0x1000, size 0x2000, and name "foo"
                  - another with base address 0x3000, size 0x4000, and name "bar"



         * - ``interrupts``
           - ``array``
           - .. code-block:: none

                Information about interrupts generated by the device, encoded as an array
                of one or more interrupt specifiers. The format of the data in this property
                varies by where the device appears in the interrupt tree. Devices with the same
                "interrupt-parent" will use the same format in their interrupts properties.

                For details, see "2.4 Interrupts and Interrupt Mapping" in
                Devicetree Specification v0.4.



             See :ref:`zephyr:dt-important-props` for more information.

           - ``compound``
           - .. code-block:: none

                Extended interrupt specifier for device, used as an alternative to
                the "interrupts" property.

                For details, see "2.4 Interrupts and Interrupt Mapping" in
                Devicetree Specification v0.4.



         * - ``interrupt-names``
           - ``string-array``
           - .. code-block:: none

                Optional names given to each interrupt generated by a device.
                The interrupts themselves are defined in either "interrupts" or
                "interrupts-extended" properties.

                For details, see "2.4 Interrupts and Interrupt Mapping" in
                Devicetree Specification v0.4.



         * - ``interrupt-parent``
           - ``phandle``
           - .. code-block:: none

                If present, this refers to the node which handles interrupts generated
                by this device.

                For details, see "2.4 Interrupts and Interrupt Mapping" in
                Devicetree Specification v0.4.



         * - ``label``
           - ``string``
           - .. code-block:: none

                Human readable string describing the device. Use of this property is
                deprecated except as needed on a case-by-case basis.

                For details, see "4.1.2 Miscellaneous Properties" in Devicetree
                Specification v0.4.



             See :ref:`zephyr:dt-important-props` for more information.

           - ``phandle-array``
           - .. code-block:: none

                Information about the device's clock providers. In general, this property
                should follow conventions established in the dt-schema binding:

                  https://github.com/devicetree-org/dt-schema/blob/main/dtschema/schemas/clock/clock.yaml

           - ``int``
           - .. code-block:: none

                This property encodes the number of <u32> cells used by address fields
                in "reg" properties in this node's children.
