 *
 *        Due to the time required for the sensor to startup, this driver is
 *        meant to be used in an asynchronous fashion. The caller must first
 *        activate the sensor by calling SENSORS_ACTIVATE(). This will trigger
 *        the sensor's startup sequence, but the call will not wait for it to
 *        complete so that the CPU can perform other tasks or drop to a low
 *        power mode.
 *
 *        Once the sensor is stable, the driver will generate a
 *        sensors_changed event.
 *
 *        The caller should then use value(TMP_007_SENSOR_TYPE_ALL) to
 *        read sensor values and latch them. Once completed successfully,
 *        individual readings can be retrieved with calls to
 *        value(TMP_007_SENSOR_TYPE_OBJECT) or
 *        value(TMP_007_SENSOR_TYPE_AMBIENT).
 *
 *        Once required readings have been taken, the caller has two options:
 *        - Turn the sensor off by calling SENSORS_DEACTIVATE, but in order
 *          to take subsequent readings SENSORS_ACTIVATE must be called again.
 *        - Leave the sensor on. In this scenario, the caller can simply keep
 *          calling value(TMP_007_SENSOR_TYPE_ALL) to read and latch new
 *          values. However keeping the sensor on will consume more energy.
