+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"
+ - interrupts : interrupt from the parent controller
+ - interrupt-controller : indicates that the controller 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";
+ interrupts = <21>;
+ interrupt-controller;
+ };
+ };
