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;
|
|
};
