The sch5636 driver runs a sanity check on loading to ensure 24*4882a593Smuzhiyunit is dealing with a Fujitsu Theseus and not with another custom SCH5636 based 25*4882a593Smuzhiyunhwmon solution. 26*4882a593Smuzhiyun 27*4882a593SmuzhiyunThe Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16 28*4882a593Smuzhiyuntemperatures. Note that the driver detects how many fan headers / 29*4882a593Smuzhiyuntemperature sensors are actually implemented on the motherboard, so you will 30*4882a593Smuzhiyunlikely see fewer temperature and fan inputs. 31*4882a593Smuzhiyun 32*4882a593SmuzhiyunThe Fujitsu Theseus hwmon solution also contains an integrated watchdog. 33*4882a593SmuzhiyunThis watchdog is fully supported by the sch5636 driver. 34*4882a593Smuzhiyun 35*4882a593SmuzhiyunAn application note describing the Theseus' registers, as well as an 36*4882a593Smuzhiyunapplication note describing the protocol for communicating with the 37*4882a593Smuzhiyunmicrocontroller is available upon request.
