+Generic device tree configuration for PECI adapters
+===================================================
+
+Required properties:
+- #address-cells : Should be <1>. Read more about client addresses below.
+- #size-cells : Should be <0>. Read more about client addresses below.
+
+The cells properties above define that an address of CPU clients of a PECI bus
+are described by a single value.
+
+Example:
+ peci0: peci-bus@0 {
+ compatible = "vendor,soc-peci";
+ reg = <0x0 0x1000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ };
+
+Generic device tree configuration for PECI clients
+==================================================
+
+Required properties:
+- compatible : Should contain name of 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>;
+ };
+ };
