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



.. code-block:: none

   Texas Instruments TMAG5273 Low-Power Linear 3D Hall-Effect Sensor with an I2C interface.

   See the specification for the default I2C address.

   The specification of the sensor can be found at:
     https://www.ti.com/lit/ds/symlink/tmag5273.pdf

     When setting the enum properties in a .dts or .dtsi file you may
     include tmag5273.h and use the macros defined there.

     Example:
     #include <zephyr/dt-bindings/sensor/tmag5273.h>

     tmag5273: tmag5273@0 {
       ...
       axis = <TMAG5273_DT_AXIS_XYZ>;
       range = <TMAG5273_DT_AXIS_RANGE_HIGH>;
     };

   .. 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

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

                Human readable string describing the sensor. It can be used to
                distinguish multiple instances of the same model (e.g., lid accelerometer
                vs. base accelerometer in a laptop) to a host operating system.

                This property is defined in the Generic Sensor Property Usages of the HID
                Usage Tables specification
                (https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).



         * - ``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.



         * - ``operation-mode``
           - ``int``
           - .. code-block:: none
