2 AST25XX SoCs.
3
4 Required Properties:
5 - #address-cells : should be 1
6 - #size-cells : should be 1
7 - #interrupt-cells : should be 1
8 - compatible : should be "aspeed,ast2400-i2c-ic"
9 or "aspeed,ast2500-i2c-ic"
10 - reg : address start and range of controller
11 - interrupts : interrupt number
12 - interrupt-controller : denotes that the controller receives and fires
13 new interrupts for child busses

15 Example:
16
17 i2c_ic: interrupt-controller@0 {
18 #address-cells = <1>;
19 #size-cells = <1>;
20 #interrupt-cells = <1>;
21 compatible = "aspeed,ast2400-i2c-ic";
22 reg = <0x0 0x40>;
23 interrupts = <12>;
24 interrupt-controller;
25 };
