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

These nodes are "qspi" bus nodes.

.. code-block:: none

   Properties defining the interface for the Nordic QSPI peripheral.

Properties

   .. 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

         * - ``sck-pin``
           - ``int``
           - .. code-block:: none

                The SCK pin to use.

                For pins P0.0 through P0.31, use the pin number. For example,
                to use P0.16 for SCK, set:

                    sck-pin = <16>;

                For pins P1.0 through P1.31, add 32 to the pin number. For
                example, to use P1.2 for SCK, set:

                    sck-pin = <34>;  /* 32 + 2 */



             This property is **required**.

         * - ``io-pins``
           - ``array``
           - .. code-block:: none

                Pin numbers associated with IO0 through IO3 signals.

                Examples:

                    io-pins = <io0-pin io1-pin>; // two pins

                    io-pins = <io0-pin io1-pin io2-pin io3-pin>; // four pins

                Either two or four pins must be configured using this property
                as shown above. The pin numbering scheme is the same as the
                sck-pin property's.



             This property is **required**.

         * - ``csn-pins``
           - ``array``
           - .. code-block:: none

                Chip select signal pin number. Exactly one pin should be
                given. The pin numbering scheme is the same as the
                sck-pin property's.



             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 "nordic,nrf-qspi" compatible.
