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;
};
