[PATCH 00/26] platform/x86/amd/hsmp: Extend socket and per-CPU sysfs

[Muthusamy Ramalingam <Muthusamy.Ramalingam@amd.com>]

This series extends the AMD HSMP sysfs interface on both the ACPI and
platform drivers. It starts with socket attribute naming cleanup and a
parser-friendly store error helper, then adds the remaining
message-backed socket and per-CPU attributes used on server platforms.

Later patches cover link/bandwidth, DIMM, SVI3, power-efficiency, and
per-CPU files. Attribute visibility follows the enabled-message bitmaps.
Probe-time discovery for optional DIMM/IO/xGMI hardware is quieted so
expected firmware misses do not flood dmesg.

The series ends with socket_temperature (HSMP_GET_TEMP_MONITOR).
