+Bindings for Intel PECI (Platform Environment Control Interface) hwmon driver.
+
+Required properties:
+- compatible
+	Should be "intel,peci-hwmon".
+
+- reg
+	Should contain address of a client CPU. Address range of CPU clients is
+	starting from 0x30 based on PECI specification.
+	<0x30> .. <0x37> (depends on the PECI_OFFSET_MAX definition)
+
+Example:
+	peci-bus@0 {
+		#address-cells = <1>;
+		#size-cells = <0>;
+		< more properties >
+
+		peci-hwmon@cpu0 {
+			compatible = "intel,peci-hwmon";
+			reg = <0x30>;
+		};
+
+		peci-hwmon@cpu1 {
+			compatible = "intel,peci-hwmon";
+			reg = <0x31>;
+		};
+	};
