+* Exynos Thermal Management Unit (TMU)
+
+** Required properties:
+
+- compatible : One of the following:
+	       "samsung,exynos4412-tmu"
+	       "samsung,exynos4210-tmu"
+	       "samsung,exynos5250-tmu"
+- interrupt-parent : The phandle for the interrupt controller
+- reg : Address range of the thermal registers
+- interrupts : Should contain interrupt for thermal system
+- clocks : The main clock for TMU device
+- clock-names : Thermal system clock name
+
+Example:
+
+	tmu@100C0000 {
+		compatible = "samsung,exynos4412-tmu";
+		interrupt-parent = <&combiner>;
+		reg = <0x100C0000 0x100>;
+		interrupts = <2 4>;
+		clocks = <&clock 383>;
+		clock-names = "tmu_apbif";
+		status = "disabled";
+	};
