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