clang-tidy: Initial commit

Added initial .clang-tidy configuration file with recommended C++ checks
aligned with the OpenBMC-approved checklist. This setup enforces modern
C++ best practices and helps catch common issues early in development.

OpenPOWER OCC Control Service

This service will handle communications to the On-Chip Controller (OCC) on Power processors. The OCC provides processor and memory temperatures, power readings, power cap support, system power mode support, and idle power saver support. OCC Control will be interfacing with the OCC to collect the temperatures and power readings, updating the system power mode, setting power caps, and idle power save parameters.

The service is started automatically when the BMC is started.

Build Project

This project can be built with meson. The typical meson workflow is: meson builddir && ninja -C builddir.

Server

The server will start automatically after BMC is powered on.

Server status: systemctl status org.open_power.OCC.Control.service

To restart the service: systemctl restart org.open_power.OCC.Control.service

Configuration

Service files are located in service_files subdirectory.
