1Ingenic SoC Interrupt Controller 2 3Required properties: 4 5- compatible : should be "ingenic,<socname>-intc". Valid strings are: 6 ingenic,jz4740-intc 7 ingenic,jz4770-intc 8 ingenic,jz4775-intc 9 ingenic,jz4780-intc 10- reg : Specifies base physical address and size of the registers. 11- interrupt-controller : Identifies the node as an interrupt controller 12- #interrupt-cells : Specifies the number of cells needed to encode an 13 interrupt source. The value shall be 1. 14- interrupt-parent : phandle of the CPU interrupt controller. 15- interrupts : Specifies the CPU interrupt the controller is connected to. 16 17Example: 18 19intc: interrupt-controller@10001000 { 20 compatible = "ingenic,jz4740-intc"; 21 reg = <0x10001000 0x14>; 22 23 interrupt-controller; 24 #interrupt-cells = <1>; 25 26 interrupt-parent = <&cpuintc>; 27 interrupts = <2>; 28}; 29
