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.
