1Loongson ls1x Interrupt Controller 2 3Required properties: 4 5- compatible : should be "loongson,ls1x-intc". Valid strings are: 6 7- reg : Specifies base physical address and size of the registers. 8- interrupt-controller : Identifies the node as an interrupt controller 9- #interrupt-cells : Specifies the number of cells needed to encode an 10 interrupt source. The value shall be 2. 11- interrupts : Specifies the CPU interrupt the controller is connected to. 12 13Example: 14 15intc: interrupt-controller@1fd01040 { 16 compatible = "loongson,ls1x-intc"; 17 reg = <0x1fd01040 0x18>; 18 19 interrupt-controller; 20 #interrupt-cells = <2>; 21 22 interrupt-parent = <&cpu_intc>; 23 interrupts = <2>; 24}; 25
