Device tree configuration for the I2C Interrupt Controller on the AST24XX and

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;

};
