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. |
