| 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; | |
| }; |
