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