Description
|
|
-----------
|
|
|
|
This driver implements support for Texas Instruments TMP401, TMP411,
|
|
and TMP431 chips. These chips implement one remote and one local
|
|
temperature sensor. Temperature is measured in degrees
|
|
Celsius. Resolution of the remote sensor is 0.0625 degree. Local
|
|
sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not
|
|
supported by the driver so far, so using the default resolution of 0.5
|
|
degree).
|
|
|
|
The driver provides the common sysfs-interface for temperatures (see
|
|
Documentation/hwmon/sysfs-interface under Temperatures).
|
|
|
|
The TMP411 and TMP431 chips are compatible with TMP401. TMP411 provides
|
|
some additional features.
|
|
|
|
* Minimum and Maximum temperature measured since power-on, chip-reset
|
|
|
|
Exported via sysfs attributes tempX_lowest and tempX_highest.
|
|
|
|
* Reset of historical minimum/maximum temperature measurements
|
|
|
|
Exported via sysfs attribute temp_reset_history. Writing 1 to this
|
|
file triggers a reset.
