36Description
37-----------
38
39This driver implements support for the National Semiconductor / Texas
40Instruments LM92 temperature sensor.
41
42Each LM92 temperature sensor supports a single temperature sensor. There are
43alarms for high, low, and critical thresholds. There's also an hysteresis to
44control the thresholds for resetting alarms.
45
46The driver also supports LM76 and Maxim MAX6633/MAX6634/MAX6635, which are
47mostly compatible but do not have a vendor ID register and therefore must be
48instantiated explicitly.

46Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635,
47which are mostly compatible. They have not all been tested, so you
48may need to use the force parameter.
