hwmon: (tmp102) Various fixes
Fixes from my driver review: http://lists.lm-sensors.org/pipermail/lm-sensors/2010-March/028051.html Only the small changes are in there, more important changes will come later separately as time permits. * Drop the remnants of the now gone detect function * The TMP102 has no known compatible chip * Include the right header files * Clarify why byte swapping of register values is needed * Strip resolution info bit from temperature register value * Set cache lifetime to 1/3 second * Don't arbitrarily reject limit values; clamp as needed * Make limit writing unconditional * Don't check for transaction types the driver doesn't use * Properly check for error when setting configuration * Report error on failed probe * Make the driver load automatically where needed * Various other minor fixes Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Steven King <sfking@fdwdc.com>

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
+sensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0
+degree 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
