      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 "fixed-partitions" compatible.

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

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

   * - Name
     - Type
     - Details

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

          Human readable string describing the device (used as device_get_binding() argument)


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

   * - ``read-only``
     - ``boolean``
     - .. code-block:: none

          if the partition is read-only or not


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

          register space


       This property is **required**.

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

   * - ``zephyr,memory-region``
     - ``string``
     - .. code-block:: none

          Signify that this node should result in a dedicated linker script
          memory region in the final executable. The region address and size
          is taken from the <reg> property, while the name is the value of
          this property. This must only be added to memory-mapped partitions,
          not partitions on external flash.
