  19. Description
  20. -----------
  21. This driver implements support for the National Semiconductor / Texas
  22. Instruments LM92 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. The driver also supports LM76 and Maxim MAX6633/MAX6634/MAX6635, which are
  27. mostly compatible but do not have a vendor ID register and therefore must be
  28. instantiated explicitly.
