PECI is designed +to support the following sideband functions: + +- Processor and DRAM thermal management +- Platform Manageability +- Processor Interface Tuning and Diagnostics +- Failure Analysis + +Required properties: +- compatible : Should be "intel,peci-client". +- reg : Should contain address of a client CPU.
