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.]

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). + |
