| 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. |
