    +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;
    + };
    + };
