|  | Description | 
|  | ----------- | 
|  |  | 
|  | The Texas Instruments TMP108 implements one temperature sensor. An alert pin | 
|  | can be set when temperatures exceed minimum or maximum values plus or minus a | 
|  | hysteresis value. (This driver does not support interrupts for the alert pin, | 
|  | and the device runs in comparator mode.) | 
|  |  | 
|  | The sensor is accurate to 0.75C 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. | 
|  | Hysteresis values can be set to 0, 1, 2, or 4C. | 
|  |  | 
|  | The TMP108 has a programmable update rate that can select between 8, 4, 1, and | 
|  | 0.5 Hz. | 
|  |  | 
|  | By default the TMP108 reads the temperature continuously. To conserve power, | 
|  | the TMP108 has a one-shot mode where the device is normally shut-down. When a | 
|  | one shot is requested the temperature is read, the result can be retrieved, | 
|  | and then the device is shut down automatically. (This driver only supports | 
|  | continuous mode.) | 
|  |  | 
|  | The driver provides the common sysfs-interface for temperatures (see | 
|  | Documentation/hwmon/sysfs-interface under Temperatures). |
