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


These property descriptions apply to "ti,ads1013"
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

         * - ``#io-channel-cells``
           - ``int``
           - This property is **required**.

             Constant value: ``1``

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

                GPIO specifier that controls power to the device.

                This property should be provided when the device has a dedicated
                switch that controls power to the device.  The supply state is
                entirely the responsibility of the device driver.

                Contrast with vin-supply.



         * - ``vin-supply``
           - ``phandle``
           - .. code-block:: none

                Reference to the regulator that controls power to the device.
                The referenced devicetree node must have a regulator compatible.

                This property should be provided when device power is supplied
                by a shared regulator.  The supply state is dependent on the
                request status of all devices fed by the regulator.

                Contrast with supply-gpios.  If both properties are provided
                then the regulator must be requested before the supply GPIOS is
                set to an active state, and the supply GPIOS must be set to an
                inactive state before releasing the regulator.





   .. 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 "ti,ads1013" compatible.

      .. list-table::

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

                Property to identify that a device can be used as wake up source.

                When this property is provided a specific flag is set into the
                device that tells the system that the device is capable of
                wake up the system.

                Wake up capable devices are disabled (interruptions will not wake up
                the system) by default but they can be enabled at runtime if necessary.



         * - ``power-domain``
           - ``phandle``
           - .. code-block:: none


                Power domain the device belongs to.

                The device will be notified when the power domain it belongs to is either
                suspended or resumed.



         * - ``zephyr,pm-device-runtime-auto``

   * - ``zephyr,vref-mv``
     - ``int``
     - .. code-block:: none

          This property can be used to specify the voltage (in millivolts)
          of the reference selected for this channel, so that applications
          can get that value if needed for some calculations.
          For the internal reference, the voltage can be usually obtained with
          a dedicated ADC API call, so there is no need to use this property
          in that case, but for other references this property can be useful.



   * - ``zephyr,acquisition-time``
     - ``int``
     - .. code-block:: none

          Acquisition time.
          Use the ADC_ACQ_TIME macro to compose the value for this property
          or pass ADC_ACQ_TIME_DEFAULT to use the default setting for a given
          hardware (e.g. when the hardware does not allow to configure the
          acquisition time).



       This property is **required**.

   * - ``zephyr,differential``
     - ``boolean``
     - .. code-block:: none

          When set, selects differential input mode for the channel. Otherwise,
          single-ended mode is used unless the zephyr,input-negative property is
          specified, in which case the differential mode is selected implicitly.



   * - ``zephyr,input-positive``
     - ``int``
     - .. code-block:: none

          Positive ADC input. Used only for drivers that select
          the ADC_CONFIGURABLE_INPUTS Kconfig option.



   * - ``zephyr,input-negative``
     - ``int``
     - .. code-block:: none

          Negative ADC input. Used only for drivers that select
          the ADC_CONFIGURABLE_INPUTS Kconfig option.
          When specified, implies the differential input mode for the channel.



   * - ``zephyr,resolution``
     - ``int``
     - .. code-block:: none

          ADC resolution to be used for the channel.



   * - ``zephyr,oversampling``
     - ``int``
     - .. code-block:: none

          Oversampling setting to be used for the channel.
          When specified, each sample is averaged from 2^N conversion results
          (where N is the provided value).



   * - ``zephyr,current-source-pin``
     - ``uint8-array``
     - .. code-block:: none

          Output pin selection for the current sources. The actual
          interpretation depends on the driver. This is used only for drivers
          which select the ADC_CONFIGURABLE_EXCITATION_CURRENT_SOURCE_PIN
          Kconfig option.



   * - ``zephyr,vbias-pins``
     - ``int``
     - .. code-block:: none

          Output pin selection for the bias voltage. The actual interpretation
          depends on the driver. This is used only for drivers which select
          the ADC_CONFIGURABLE_VBIAS_PIN Kconfig option.
