+Description
+-----------
+
+The Texas Instruments TMP102 implements one temperature sensor. Limits can be
+set through the Overtemperature Shutdown register and Hysteresis register. The
+sensor is accurate to 0.5 degrees over the range of -25 to +85 C, and to 1.0
+degrees from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The
+operating temperature has a minimum of -55 C and a maximum of +150 C.
+
+The TMP102 has a programmable update rate that can select between 8, 4, 1, and
+0.5 Hz. (Currently the driver only supports the default of 4 Hz).
+
+The driver provides the common sysfs-interface for temperatures (see
+/Documentation/hwmon/sysfs-interface under Temperatures).
