| 14 | ----------- |
| 15 | |
| 16 | The Texas Instruments TMP102 implements one temperature sensor. Limits can be |
| 17 | set through the Overtemperature Shutdown register and Hysteresis register. The |
| 18 | sensor is accurate to 0.5 degrees over the range of -25 to +85 C, and to 1.0 |
| 19 | degrees from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The |
| 20 | operating temperature has a minimum of -55 C and a maximum of +150 C. |
| 21 | |
| 22 | The TMP102 has a programmable update rate that can select between 8, 4, 1, and |
| 23 | 0.5 Hz. (Currently the driver only supports the default of 4 Hz). |
| 24 | |
| 25 | The driver provides the common sysfs-interface for temperatures (see |
| 26 | /Documentation/hwmon/sysfs-interface under Temperatures). |
