| 23 | Description |
| 24 | ----------- |
| 25 | |
| 26 | This driver implements support for the National Semiconductor LM92 |
| 27 | temperature sensor. |
| 28 | |
| 29 | Each LM92 temperature sensor supports a single temperature sensor. There are |
| 30 | alarms for high, low, and critical thresholds. There's also an hysteresis to |
| 31 | control the thresholds for resetting alarms. |
| 32 | |
| 33 | Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635, |
| 34 | which are mostly compatible. They have not all been tested, so you |
| 35 | may need to use the force parameter. |
