These chips implement one or two +remote and one local temperature sensors. 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.rst 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. + +TMP432 is compatible with TMP401 and TMP431. It supports two external +temperature sensors. + +TMP461 is compatible with TMP401. It supports offset correction +that is applied to the remote sensor. + +* Sensor offset values are temperature values + + Exported via sysfs attribute tempX_offset |
