+===========================================
+C-SKY Multi-processors Interrupt Controller
+===========================================
+
+C-SKY Multi-processors Interrupt Controller is designed for ck807/ck810/ck860
+SMP soc, and it also could be used in non-SMP system.
+
+Interrupt number definition:
+
+  0-15  : software irq, and we use 15 as our IPI_IRQ.
+ 16-31  : private  irq, and we use 16 as the co-processor timer.
+ 31-1024: common irq for soc ip.
+

+	Description: Describes SMP interrupt controller
+
+	PROPERTIES
+
+        - compatible
+		Usage: required
+                Value type: <string>
+                Definition: must be "csky,mpintc"
+        - interrupt-cells
+                Usage: required
+                Value type: <u32>
+                Definition: must be <1>
+        - interrupt-controller:
+                Usage: required
+
+Examples:
+---------
+
+	intc: interrupt-controller {
+		compatible = "csky,mpintc";
+		#interrupt-cells = <1>;
+		interrupt-controller;
+	};
