1 Device tree configuration for the I2C Interrupt Controller on the AST24XX and
2 AST25XX SoCs.

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

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 };
