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

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 -/Documentation/hwmon/sysfs-interface under Temperatures). - +Documentation/hwmon/sysfs-interface under Temperatures). |
