+The ADT7410 is a temperature sensor with rated temperature range of -55°C to
++150°C. It has a high accuracy of +/-0.5°C and can be operated at a resolution
+of 13 bits (0.0625°C) or 16 bits (0.0078°C). The sensor provides an INT pin to
+indicate that a minimum or maximum temperature set point has been exceeded, as
+well as a critical temperature (CT) pin to indicate that the critical
+temperature set point has been exceeded. Both pins can be set up with a common
+hysteresis of 0°C - 15°C and a fault queue, ranging from 1 to 4 events. Both
+pins can individually set to be active-low or active-high, while the whole
+device can either run in comparator mode or interrupt mode. The ADT7410
+supports continous temperature sampling, as well as sampling one temperature
+value per second or even justget one sample on demand for power saving.
+Besides, it can completely power down its ADC, if power management is
+Configuration Notes
+Since the device uses one hysteresis value, which is an offset to minimum,
+maximum and critical temperature, it can only be set for temp#_max_hyst.
+However, temp#_min_hyst and temp#_crit_hyst show their corresponding
+The device is set to 16 bit resolution and comparator mode.
