  33 Description
  34 -----------
  35
  36 This driver implements support for Texas Instruments TMP401, TMP411,
  37 TMP431, TMP432, TMP435, and TMP461 chips. These chips implement one or two
  38 remote and one local temperature sensors. Temperature is measured in degrees
  39 Celsius. Resolution of the remote sensor is 0.0625 degree. Local
  40 sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not
  41 supported by the driver so far, so using the default resolution of 0.5
  42 degree).
  43
  44 The driver provides the common sysfs-interface for temperatures (see
  45 Documentation/hwmon/sysfs-interface under Temperatures).
  46
  47 The TMP411 and TMP431 chips are compatible with TMP401. TMP411 provides
  48 some additional features.
  49
  50 * Minimum and Maximum temperature measured since power-on, chip-reset
  51
  52   Exported via sysfs attributes tempX_lowest and tempX_highest.
  53
  54 * Reset of historical minimum/maximum temperature measurements
  55
  56   Exported via sysfs attribute temp_reset_history. Writing 1 to this
  57   file triggers a reset.
  58
  59 TMP432 is compatible with TMP401 and TMP431. It supports two external
  60 temperature sensors.
  61
  62 TMP461 is compatible with TMP401. It supports offset correction
  63 that is applied to the remote sensor.
  64
  65 * Sensor offset values are temperature values
  66
  67   Exported via sysfs attribute tempX_offset
