Subject: [PATCH linux dev-4.10 0/6] Add support PECI and PECI hwmon drivers

From: Jae Hyun Yoo <jae.hyun.yoo@...el.com>

Hello,

This patch set provides support for PECI of AST2400/2500 which can give us PECI
functionalities such as temperature monitoring, platform manageability,
processor diagnostics and failure analysis. Also provides generic peci.h and
peci_ioctl.h headers to provide compatibility to peci drivers that can be
implemented later e.g. Nuvoton's BMC SoC family.

The misc peci driver can be used as a multi-purpose PECI controller driver which
serializes all PECI transactions that coming from user space and from other
kernel modules. This misc peci driver could be replaced with other BMC chipsets'
implementation if the implementation provide compatible 'peci_ioctl'
inter-module call and ioctl scheme defined in peci.h and peci_ioctl.h files.

The hwmon peci driver implements a generic PECI hwmon feature which is running
with a PECI misc driver supports compatible native PECI command suite for
retrieving temperatures of the CPU package, CPU cores and DIMM components.

Please review.

-Jae
