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;

        };

    };
