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;
};
};
