Hi there.

I have a headache with linux bug
https://bugzilla.kernel.org/show_bug.cgi?id=153281

and i'm one from many others that still suffered from the described issue. Personally i was able to move forward a bit. In particular,

1) with a  great soft that manipulates with fan speed ranges
https://github.com/dominiksalvet/asus-fan-control/issues/43

i was able to understand how maximal mode is activated at very low level in the so-called embedded controller in addresses

0x0521 and 0x0522.

2) It seems i understand that there is another driver/hardware mode that activates maximal mode eternally.

3) I disassembled my dsdt tables and found no more destructive code that could change maximal mode back

================

So, i'm interest in people here who could help me cruising in kernel sources to understand who else can communicate with an embedded controller. For now, I'm interested how driver asus-nb-wmi registers it's controlling chipset to hwmon so
/sys/devices/platform/asus-nb-wmi/hwmon/hwmon5

node is created.

From sensors i see that it is a
asus-isa-0000
Adapter: ISA adapter
cpu_fan:     1900 RPM
temp1:        +53.0°C

and i wonder how it registered.
