+Samsung's Multi Core Timer (MCT)
+
+The Samsung's Multi Core Timer (MCT) module includes two main blocks, the
+global timer and CPU local timers. The global timer is a 64-bit free running
+up-counter and can generate 4 interrupts when the counter reaches one of the
+four preset counter values. The CPU local timers are 32-bit free running
+down-counters and generate an interrupt when the counter expires. There is
+one CPU local timer instantiated in MCT for every CPU in the system.
+
+Required properties:
+
+- compatible: should be "samsung,exynos4210-mct".
+  (a) "samsung,exynos4210-mct", for mct compatible with Exynos4210 mct.
+  (b) "samsung,exynos4412-mct", for mct compatible with Exynos4412 mct.
+
+- reg: base address of the mct controller and length of the address space
+  it occupies.
+
+- interrupts: the list of interrupts generated by the controller. The following
+  should be the order of the interrupts specified. The local timer interrupts
+  should be specified after the four global timer interrupts have been
+  specified.
+
+	0: Global Timer Interrupt 0
+	1: Global Timer Interrupt 1
+	2: Global Timer Interrupt 2
+	3: Global Timer Interrupt 3
+	4: Local Timer Interrupt 0
+	5: Local Timer Interrupt 1
+	6: ..
+	7: ..
+	i: Local Timer Interrupt n
+
+Example 1: In this example, the system uses only the first global timer
+	   interrupt generated by MCT and the remaining three global timer
+	   interrupts are unused. Two local timer interrupts have been
+	   specified.
+
+	mct@10050000 {
+		compatible = "samsung,exynos4210-mct";
+		reg = <0x10050000 0x800>;
+		interrupts = <0 57 0>, <0 0 0>, <0 0 0>, <0 0 0>,
+			     <0 42 0>, <0 48 0>;
+	};
+
+Example 2: In this example, the MCT global and local timer interrupts are
+	   connected to two seperate interrupt controllers. Hence, an
+	   interrupt-map is created to map the interrupts to the respective
+	   interrupt controllers.
+
+	mct@101C0000 {
+		compatible = "samsung,exynos4210-mct";
+		reg = <0x101C0000 0x800>;
+		interrupt-controller;
+		#interrups-cells = <2>;
+		interrupt-parent = <&mct_map>;
+		interrupts = <0 0>, <1 0>, <2 0>, <3 0>,
+			     <4 0>, <5 0>;
+
+		mct_map: mct-map {
+			#interrupt-cells = <2>;
+			#address-cells = <0>;
+			#size-cells = <0>;
+			interrupt-map = <0x0 0 &combiner 23 3>,
+					<0x4 0 &gic 0 120 0>,
+					<0x5 0 &gic 0 121 0>;
+		};
+	};
