+Aspeed AST25XX and AST26XX SCU Interrupt Controller
+
+Required Properties:
+ - #interrupt-cells		: must be 1
+ - compatible			: must be "aspeed,ast2500-scu-ic",
+				  "aspeed,ast2600-scu-ic0" or
+				  "aspeed,ast2600-scu-ic1"
+ - reg				: address and size of the SCU register
+				  associated with the controller
+ - interrupts			: interrupt from the parent controller
+ - interrupt-controller		: indicates that the controlle receives and
+				  fires new interrupts for child busses
+
+Example:
+
+    syscon@1e6e2000 {
+        ranges = <0 0x1e6e2000 0x1a8>;
+
+        scu_ic: interrupt-controller@18 {
+            #interrupt-cells = <1>;
+            compatible = "aspeed,ast2500-scu-ic";
+            reg = <0x18 0x04>;
+            interrupts = <21>;
+            interrupt-controller;
+        };
+    };
