16-----------
17
18SMSC SCH5636 Super I/O chips include an embedded microcontroller for
19hardware monitoring solutions, allowing motherboard manufacturers to create
20their own custom hwmon solution based upon the SCH5636.
21
22Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based
23hwmon solution. The sch5636 driver runs a sanity check on loading to ensure
24it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based
25hwmon solution.
26
27The Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16
28temperatures. Note that the driver detects how many fan headers /
29temperature sensors are actually implemented on the motherboard, so you will
30likely see fewer temperature and fan inputs.
31
32The Fujitsu Theseus hwmon solution also contains an integrated watchdog.
33This watchdog is fully supported by the sch5636 driver.

35An application note describing the Theseus' registers, as well as an
36application note describing the protocol for communicating with the
37microcontroller is available upon request. Please mail me if you want a copy.
