The BMC Teutates is the Eleventh generation of Superior System
monitoring and thermal management solution. It is builds on the basic
functionality of the BMC Theseus and contains several new features and
enhancements. It can monitor up to 4 voltages, 16 temperatures and
8 fans. It also contains an integrated watchdog which is currently
implemented in this driver.
hwmon: (ftsteutates) Replace fanX_source with pwmX_auto_channels_temp Replace the nonstandard fanX_source attributes with the standardized pwmX_auto_channels_temp attributes and document the special behaviour associated with those attributes. Tested on a Fujitsu DS3401-B1. Signed-off-by: Armin Wolf <W_Armin@gmx.de> Link: https://lore.kernel.org/r/20230105225107.58308-3-W_Armin@gmx.de Signed-off-by: Guenter Roeck <linux@roeck-us.net>

The ``pwmX_auto_channels_temp`` attributes show which temperature sensor
is currently driving which fan channel. This value might dynamically change
during runtime depending on the temperature sensor selected by
the fan control circuit.
hwmon: (ftsteutates) Fix scaling of measurements A user complained that the ftsteutates driver was displaying bogus values since its introduction. This happens because the sensor measurements need to be scaled in order to produce meaningful results: - the fan speed needs to be multiplied by 60 since its in RPS - the temperature is in degrees celsius and needs an offset of 64 - the voltage is in 1/256 of 3.3V The offical datasheet says the voltage needs to be divided by 256, but this is likely an off-by-one-error, since even the BIOS devides by 255 (otherwise 3.3V could not be measured). The voltage channels additionally need a board-specific multiplier, however this can be done by the driver since its board-specific. The reason the missing scaling of measurements is the way Fujitsu used this driver when it was still out-of-tree. Back then, all scaling was done in userspace by libsensors, even the generic one. Tested on a Fujitsu DS3401-B1.

The 4 voltages require a board-specific multiplier, since the BMC can
only measure voltages up to 3.3V and thus relies on voltage dividers.
Consult your motherboard manual for details.
