  8. Description
  9. -----------
  10. SMSC SCH5636 Super I/O chips include an embedded microcontroller for
  11. hardware monitoring solutions, allowing motherboard manufacturers to create
  12. their own custom hwmon solution based upon the SCH5636.
  13. Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based
  14. hwmon solution. The sch5636 driver runs a sanity check on loading to ensure
  15. it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based
  16. hwmon solution.
  17. The Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16
  18. temperatures. Note that the driver detects how many fan headers /
  19. temperature sensors are actually implemented on the motherboard, so you will
  20. likely see fewer temperature and fan inputs.
  21. The Fujitsu Theseus hwmon solution also contains an integrated watchdog.
  22. This watchdog is fully supported by the sch5636 driver.
  23. An application note describing the Theseus' registers, as well as an
  24. application note describing the protocol for communicating with the
  25. microcontroller is available upon request. Please mail me if you want a copy.
