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>

Description
|
|
-----------
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
To clear a temperature or fan alarm, execute the following command with the
|
|
correct path to the alarm file::
|
|
|
|
echo 0 >XXXX_alarm
