+* Generic PECI (Platform Environment Control Interface) hwmon driver.
+
+Dependency:
+- This driver uses a PECI misc driver as a controller interface so one of PECI
+  misc drivers which provides compatible ioctls has to be enabled.
+
+Required properties:
+- compatible: "peci-hwmon"
+- cpu-id: Should contain CPU socket ID
+	- 0 ~ 7
+
+Optional properties:
+- show-core: If this protperty is defined, core tmeperature attrubites will be
+	     enumerated.
+- dimm-nums: Should contain the number of DIMM slots that attached to each CPU
+	     which is indicated by cpu-id.
+	0 ~ 16 (default: 16)
+	     In case of 0, DIMM temperature attrubites will not be enumerated.
+
+Example:
+	peci-hwmon0 {
+		compatible = "peci-hwmon";
+		cpu-id = <0>;
+		show-core;
+		dimm-nums = <16>;
+	};
+
+	peci-hwmon1 {
+		compatible = "peci-hwmon";
+		cpu-id = <1>;
+		show-core;
+		dimm-nums = <16>;
+	};
