  25Description
  26-----------
  27
  28This driver implements support for the National Semiconductor LM92
  29temperature sensor.
  30
  31Each LM92 temperature sensor supports a single temperature sensor. There are
  32alarms for high, low, and critical thresholds. There's also an hysteresis to
  33control the thresholds for resetting alarms.
  34
  35Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635,
  36which are mostly compatible. They have not all been tested, so you
  37may need to use the force parameter.
