+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>;
+		};
+	};
