   ADP5585 GPIO Controller

Properties
**********

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


These property descriptions apply to "adi,adp5585-gpio"
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.

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

         * - Name
           - Type
           - Details

         * - ``gpio-controller``
           - ``boolean``
           - .. code-block:: none

                Convey's this node is a GPIO controller


             This property is **required**.

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

                Number of items to expect in a GPIO specifier


             This property is **required**.

             Constant value: ``2``

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

                Number of GPIOs available on port expander.



             Default value: ``32``

             Constant value: ``13``

         * - ``gpio-reserved-ranges``
           - ``array``
           - .. code-block:: none

                Ranges of GPIOs reserved unavailable on port expander.
                The ADP5585 has 10 GPIO lines divided in 2 groups. GPIO number
                5, 6, 7 is reserved. That's to say, GPIO R0~R4 occupy line
                number 0~4, GPIO C0~C4 occupy line number 8~12.



             This property is **required**.

             Constant value: ``[5, 3]``

         * - ``gpio-line-names``
           - ``string-array``
           - .. code-block:: none

                This is an array of strings defining the names of the GPIO lines
                going out of the GPIO controller





   .. 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 "adi,adp5585-gpio" compatible.

      (None)


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

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

   * - Name
     - Type
     - Details

   * - ``gpio-hog``
     - ``boolean``
     - .. code-block:: none

          Conveys this node is a GPIO hog.



       This property is **required**.

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

          This is an array of GPIO specifiers (e.g. pin, flags) to be hogged. The number of array
          entries must be an integer multiple of the number of GPIO specifier cells for the parent
          GPIO controller.



       This property is **required**.

   * - ``input``
     - ``boolean``
     - .. code-block:: none

          If this property is set, the GPIO is configured as an input. This property takes
          precedence over the output-low and output-high properties.



   * - ``output-low``
     - ``boolean``
     - .. code-block:: none

          If this property is set, the GPIO is configured as an output set to logical low. This
          property takes precedence over the output-high property.



   * - ``output-high``
     - ``boolean``
     - .. code-block:: none

          If this property is set, the GPIO is configured as an output set to logical high.



   * - ``line-name``
     - ``string``
     - .. code-block:: none

          Optional GPIO line name.



Specifier cell names
