Jean Delvare cff37c9e82 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

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 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 Documentation/hwmon/sysfs-interface under Temperatures).
