    1 Device tree configuration for the I2C Interrupt Controller on the AST24XX and
    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
   14 
   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 };
