2022-02-09peci: Add peci-cpu driverIwona Winiarska1-0/+15
PECI is an interface that may be used by different types of devices. Add a peci-cpu driver compatible with Intel processors. The driver is responsible for handling auxiliary devices that can subsequently be used by other drivers (e.g. hwmons).

2022-02-09peci: Add peci-aspeed controller driverJae Hyun Yoo1-0/+6
ASPEED AST24xx/AST25xx/AST26xx SoCs support the PECI electrical interface (a.k.a PECI wire) that provides a communication channel with Intel processors. This driver allows BMC to discover devices connected to it and communicate with them using PECI protocol.

2022-02-09peci: Add core infrastructureIwona Winiarska1-0/+15
Intel processors provide access for various services designed to support processor and DRAM thermal management, platform manageability and processor interface tuning and diagnostics. Those services are available via the Platform Environment Control Interface (PECI) that provides a communication channel between the processor and the Baseboard Management Controller (BMC) or other platform management device. This change introduces PECI subsystem by adding the initial core module and API for controller drivers.
