- AST25XX SoCs.
- Required Properties:
- - #address-cells : should be 1
- - #size-cells : should be 1
- - #interrupt-cells : should be 1
- - compatible : should be "aspeed,ast2400-i2c-ic"
- or "aspeed,ast2500-i2c-ic"
- - reg : address start and range of controller
- - interrupts : interrupt number
- - interrupt-controller : denotes that the controller receives and fires
- new interrupts for child busses
- Example:
- i2c_ic: interrupt-controller@0 {
- #address-cells = <1>;
- #size-cells = <1>;
- #interrupt-cells = <1>;
- compatible = "aspeed,ast2400-i2c-ic";
- reg = <0x0 0x40>;
- interrupts = <12>;
- interrupt-controller;
- };
