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. Address range of CPU + clients starts from 0x30 based on PECI specification. + +Example: + peci-bus@0 { + compatible = "vendor,soc-peci"; + reg = <0x0 0x1000>; + #address-cells = <1>; + #size-cells = <0>; + + peci-client@30 { + compatible = "intel,peci-client"; + reg = <0x30>; + }; + + peci-client@31 { + compatible = "intel,peci-client"; + reg = <0x31>; + }; + };
