From beb1b6bbf2b448b97b9611200eb4b5a555336c60 Mon Sep 17 00:00:00 2001 From: Steven King Date: Thu, 27 May 2010 19:58:56 +0200 Subject: 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).

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). + -- cgit
