Or maybe even drivers/acpi/thermal.c, which claims every Thermal Zone

Documentation/thermal/sysfs-api.txt is. acpi/thermal.c looks tied
into the drivers/thermal stuff (it registers "thermal_zone" devices),
but not to hwmon.
Err, I still don't think I'm catching your drift but let me stop you
right there: amd_nb is not there only for hwmon/k10temp. It is a small
interface glue if you will, which exports the CPU functionality in PCI
config space to other consumers.
Also, thermal and hwmon are orthogonal, just like hwmon and iio. One would
typically have a driver in one subsystem, in some cases bridging to the
other subsystem, but one would not have drivers in both subsystems.
I think Bjorn is suggesting that the k10temp driver should move to the
thermal subsystem, though I don't really understand what that has to do
with finding the correct PCI device(s) to query. Or maybe I misunderstand.

So it is not really a driver - it is used by drivers to talk/query CPU
settings through it.
With that said, I don't think I understand all that talk about PNP IDs
and ACPI methods. But maybe I'm missing something...
So what's up?
