Loongson ls1x Interrupt Controller Required properties: - compatible : should be "loongson,ls1x-intc". Valid strings are: - reg : Specifies base physical address and size of the registers. - interrupt-controller : Identifies the node as an interrupt controller - #interrupt-cells : Specifies the number of cells needed to encode an interrupt source. The value shall be 2. - interrupts : Specifies the CPU interrupt the controller is connected to. Example: intc: interrupt-controller@1fd01040 { compatible = "loongson,ls1x-intc"; reg = <0x1fd01040 0x18>; interrupt-controller; #interrupt-cells = <2>; interrupt-parent = <&cpu_intc>; interrupts = <2>; };
