Small Update

In addition i searched drivers/hwmon/it87.c in order to find the patched code from kernel 4.5-rc5.
Unfortunately i found no code changes from Patch v3 (i tested about 5 patches).
Should it not be patched within 4.5-rc1 or do i miss here something?
Does it say anywhere that the patches were reviewed and/or accepted
for upstream integration ?
Problem is that there is hardly anyone willing to review hwmon kernel
patches nowadays, meaning they have to go in unreviewed or not at all.
Given the complexity and scope of the series, I don't want to just push
the patches into the upstream kernel without review. With that in mind,
it may take a while for the code to be upstream.
I see. You wrote that it should go up with rc-1, so i thought it is already there, my mistake.
Second question
Is it possible to take your code from github to patch/replace it in another kernel, like 4.3 / 4.4 ?
Yes, that should be possible. I have been running it on earlier kernels
myself.
With GitHub module code for it87 chip's and a boot parameter "acpi_enforce_resources=lax"
i was able to load it.

If it is connected. On most motherboards it isn't.
Kernel 4.3.5 with Debian Testing (Stretch)
sensors version 3.4.0 with libsensors version 3.4.0
fancontrol 3.4.0-2
I'll try to get that names step by step. Further i tried fancontrol, i got funny stuff with fan5.
It seems to be that PWM values from fan5 are inverted.
Following fancontrol setting stops all fans.

I tried some different EFI settings with system fans (Silent, Normal, PWM per degree) without
any changes. Fan3 works out of the box. I will check all other fans soon.
Any idea how to fix that?
Sorry, no.
I prefer to stick with automatic fan control; I consider it to be less risky,
since it keeps working even if the user space code fails. the Super-IO chips usually
to a pretty good job.
