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"

  • 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;
};
