Top level properties
====================


These property descriptions apply to "fixed-layout"
nodes themselves. This page also describes child node
properties in the following sections.

.. tabs::

   .. group-tab:: Node specific properties

      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-layout" compatible.

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

         * - Name

         * - ``#address-cells``
           - ``int``
           - .. code-block:: none

                Number of cells required to represent a child node's
                reg property address.



             Constant value: ``1``

         * - ``#size-cells``
           - ``int``
           - .. code-block:: none

                Number of cells required to represent a child node's size.

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

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

   * - Name
     - Type
     - Details

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

          This should be in the format <OFFSET SIZE>, where OFFSET
          is the offset of the NVMEM cell relative to the base
          address of the parent memory, and SIZE is the size of
          the cell in bytes.



       This property is **required**.

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

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

          Set this property if the cell is read-only.
