| 12 | Description |
| 13 | ----------- |
| 14 | |
| 15 | SMSC SCH5636 Super I/O chips include an embedded microcontroller for |
| 16 | hardware monitoring solutions, allowing motherboard manufacturers to create |
| 17 | their own custom hwmon solution based upon the SCH5636. |
| 18 | |
| 19 | Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based |
| 20 | hwmon solution. The sch5636 driver runs a sanity check on loading to ensure |
| 21 | it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based |
| 22 | hwmon solution. |
| 23 | |
| 24 | The Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16 |
| 25 | temperatures. Note that the driver detects how many fan headers / |
| 26 | temperature sensors are actually implemented on the motherboard, so you will |
| 27 | likely see fewer temperature and fan inputs. |
| 28 | |
| 29 | An application note describing the Theseus' registers, as well as an |
| 30 | application note describing the protocol for communicating with the |
| 31 | microcontroller is available upon request. Please mail me if you want a copy. |
