  Description

  This driver implements support for Texas Instruments TMP401, TMP411,
c0a686018   Andrew F. Davis   hwmon: (tmp401) A...

37
  TMP431, TMP432, TMP435, and TMP461 chips. 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
a1fac92b8   Guenter Roeck   hwmon: (tmp401) A...
44
  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.

  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
