The sch5636 driver runs a sanity check on loading to ensure +it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based +hwmon solution. + +The Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16 +temperatures. Note that the driver detects how many fan headers / +temperature sensors are actually implemented on the motherboard, so you will +likely see fewer temperature and fan inputs. + +An application note describing the Theseus' registers, as well as an +application note describing the protocol for communicating with the +microcontroller is available upon request.
