0001 Device tree configuration for the I2C Interrupt Controller on the AST24XX and
0002 AST25XX SoCs.
0003
0004 Required Properties:
0005 - #address-cells : should be 1
0006 - #size-cells : should be 1
0007 - #interrupt-cells : should be 1
0008 - compatible : should be "aspeed,ast2400-i2c-ic"
0009 or "aspeed,ast2500-i2c-ic"
0010 - reg : address start and range of controller
0011 - interrupts : interrupt number
0012 - interrupt-controller : denotes that the controller receives and fires
0013 new interrupts for child busses
0014
0015 Example:
0016
0017 i2c_ic: interrupt-controller@0 {
0018 #address-cells = <1>;
0019 #size-cells = <1>;
0020 #interrupt-cells = <1>;
0021 compatible = "aspeed,ast2400-i2c-ic";
0022 reg = <0x0 0x40>;
0023 interrupts = <12>;
0024 interrupt-controller;
0025 };
