| 36 | Description | |
| 37 | ----------- | |
| 38 | ||
| 39 | This driver implements support for the National Semiconductor LM92 | |
| 40 | temperature sensor. | |
| 41 | ||
| 42 | Each LM92 temperature sensor supports a single temperature sensor. There are | |
| 43 | alarms for high, low, and critical thresholds. There's also an hysteresis to | |
| 44 | control the thresholds for resetting alarms. | |
| 45 | ||
| 46 | Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635, | |
| 47 | which are mostly compatible. They have not all been tested, so you | |
| 48 | may need to use the force parameter. |
