  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>;
    };

compatible: "ti,tmag5273"

include: [sensor-device.yaml, i2c-device.yaml]
