18 | Description | ||
19 | ----------- | ||
20 | |||
21 | This driver implements support for Texas Instruments TMP401 and | ||
22 | TMP411 chips. These chips implements one remote and one local | ||
23 | temperature sensor. Temperature is measured in degrees | ||
24 | Celsius. Resolution of the remote sensor is 0.0625 degree. Local | ||
25 | sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not | ||
26 | supported by the driver so far, so using the default resolution of 0.5 | ||
27 | degree). | ||
28 | |||
29 | The driver provides the common sysfs-interface for temperatures (see | ||
30 | /Documentation/hwmon/sysfs-interface under Temperatures). | ||
31 | |||
32 | The TMP411 chip is compatible with TMP401. It provides some additional | ||
33 | features. | ||
34 | |||
35 | * Minimum and Maximum temperature measured since power-on, chip-reset | ||
36 | |||
37 | Exported via sysfs attributes tempX_lowest and tempX_highest. | ||
38 | |||
39 | * Reset of historical minimum/maximum temperature measurements | ||
40 | |||
41 | Exported via sysfs attribute temp_reset_history. Writing 1 to this | ||
42 | file triggers a reset. | ||
