+* Intel PECI client bindings
+
+PECI (Platform Environment Control Interface) is a one-wire bus interface that
+provides a communication channel from PECI clients in Intel processors and
+chipset components to external monitoring or control devices. 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. According to the PECI
+ specification, client addresses start from 0x30.
+
+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>;
+ };
+ };
