c59b9a4f8d amdtemp(4): Add support for Family 17h CCD sensors
Probe Family 17h CPUs for up to 4 (Zen, Zen+) or 8 (Zen2) CCD temperature
sensors.  These were discovered by Ondrej Čerman
(https://github.com/ocerman) and collaborators experimentally, and are not
currently documented in any datasheet I have access to.

e49ec46114 amdtemp(4): Add support for Family 15h, Model >=60h
Family 15h is a bit of an oddball.  Early models used the same temperature
register and spec (mostly[1]) as earlier CPU families.

Model 60h-6Fh and 70-7Fh use something more like Family 17h's Service
Management Network, communicating with it in a similar fashion.  To support
them, add support for their version of SMU indirection to amdsmn(4) and use
it in amdtemp(4) on these models.

While here, clarify some of the deviceid macros in amdtemp(4) that were
added with arbitrary, incorrect family numbers, and remove ones that were
not used.  Additionally, clarify intent and condition of heterogenous
multi-socket system detection.

[1]: 15h adds the "adjust range by -49°C if a certain condition is met,"
which previous families did not have.

9d49c4229a amdsmn(4)/amdtemp(4): Attach to Ryzen 2 hostbridges
As reported, tested, and patch supplied by Johannes.

There may be future work to do to support multiple sensors, but for now, any
sensor at all is a strict improvement for Ryzen 2 systems.

329e817fcc Reapply, with minor tweaks, r338025, from the original commit:
Remove unused and easy to misuse PNP macro parameter

Inspired by r338025, just remove the element size parameter to the
MODULE_PNP_INFO macro entirely.  The 'table' parameter is now required to
have correct pointer (or array) type.  Since all invocations of the macro
already had this property and the emitted PNP data continues to include the
element size, there is no functional change.

Mostly done with the coccinelle 'spatch' tool:

  $ cat modpnpsize0.cocci
    @normaltables@
    identifier b,c;
    expression a,d,e;
    declarer MODULE_PNP_INFO;
    @@
     MODULE_PNP_INFO(a,b,c,d,
    -sizeof(d[0]),
     e);

    @singletons@
    identifier b,c,d;
    expression a;
    declarer MODULE_PNP_INFO;
    @@
     MODULE_PNP_INFO(a,b,c,&d,
    -sizeof(d),
     1);

  $ rg -l MODULE_PNP_INFO -- sys | \
    xargs spatch --in-place --sp-file modpnpsize0.cocci

(Note that coccinelle invokes diff(1) via a PATH search and expects diff to
tolerate the -B flag, which BSD diff does not.  So I had to link gdiff into
PATH as diff to use spatch.)

Tinderbox'd (-DMAKE_JUST_KERNELS).

b8e771e97a Back out r338035 until Warner is finished churning GSoC PNP patches
I was not aware Warner was making or planning to make forward progress in
this area and have since been informed of that.

It's easy to apply/reapply when churn dies down.

a64bf59c49 Add PNP metadata to a few drivers
An eventual devd(8) or other component should be able to scan buses and
automatically load drivers that match device ids described in this metadata.

1b93938ae4 amdsmn(4): Do not probe not matching hostbridges
Similar to r323195, but for amdsmn(4) driver (which borrowed some design).

Ignore hostbs that do not match our PCI device id criteria.

907f50fe04 Add smn(4) driver for AMD System Management Network
AMD Family 17h CPUs have an internal network used to communicate between
the host CPU and the PSP and SMU coprocessors.  It exposes a simple
32-bit register space.
