  Description
  -----------
  
  This driver implements support for Texas Instruments TMP401 and
  TMP411 chips. These chips implements 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 chip is compatible with TMP401. It 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.
