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



.. code-block:: none

   STM32N6 CPU Clock.

   Describes the STM32N6 CPU clock multiplexer. On STM32N6, this is the CPU
   clock that feeds the SysTick.

   For instance:
   &cpusw {
     clocks = <&rcc STM32_SRC_IC1 CPU_SEL(3)>;
     clock-frequency = <DT_FREQ_M(600)>;
     status = "okay";
   };

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

         * - ``clock-frequency``
           - ``int``
           - .. code-block:: none

                default frequency in Hz for CPU clock (sysa_ck/sys_cpu_ck)



             This property is **required**.



   .. 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 "st,stm32n6-cpu-clock-mux" compatible.

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

         * - Name
           - Type
           - Details

         * - ``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.

         * - ``clocks``
           - ``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:
