26Description
27-----------
28
29This driver implements support for Texas Instruments TMP401, TMP411,
30TMP431, and TMP432 chips. These chips implement one or two remote and
31one local temperature sensors. Temperature is measured in degrees
32Celsius. Resolution of the remote sensor is 0.0625 degree. Local
33sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not
34supported by the driver so far, so using the default resolution of 0.5
35degree).
36
37The driver provides the common sysfs-interface for temperatures (see
38Documentation/hwmon/sysfs-interface under Temperatures).
39
40The TMP411 and TMP431 chips are compatible with TMP401. TMP411 provides
41some additional features.
42
43* Minimum and Maximum temperature measured since power-on, chip-reset
44
45  Exported via sysfs attributes tempX_lowest and tempX_highest.
46
47* Reset of historical minimum/maximum temperature measurements
48
49  Exported via sysfs attribute temp_reset_history. Writing 1 to this
50  file triggers a reset.
51
52TMP432 is compatible with TMP401 and TMP431. It supports two external
53temperature sensors.
