hwmon: Driver for TI TMP102 temperature sensor
Driver for the TI TMP102. The TI TMP102 is similar to the LM75. It differs from the LM75 by having a 16-bit conf register and the temp registers have a minimum resolution of 12 bits; the extended conf register can select 13-bit resolution (which this driver does) and also change the update rate (which this driver currently doesn't use). [JD: Fix tmp102_exit tag, must be __exit, not __init.] Signed-off-by: Steven King <sfking@fdwdc.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

+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).
