  19. Description
  20. -----------
  21. This driver implements support for the National Semiconductor LM92
  22. temperature sensor.
  23. Each LM92 temperature sensor supports a single temperature sensor. There are
  24. alarms for high, low, and critical thresholds. There's also an hysteresis to
  25. control the thresholds for resetting alarms.
  26. Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635,
  27. which are mostly compatible. They have not all been tested, so you
  28. may need to use the force parameter.
