1* Marvell MMP Interrupt controller
2
3Required properties:
4- compatible : Should be "mrvl,mmp-intc", "mrvl,mmp2-intc" or
5  "mrvl,mmp2-mux-intc"
6- reg : Address and length of the register set of the interrupt controller.
7  If the interrupt controller is intc, address and length means the range
8  of the whold interrupt controller. If the interrupt controller is mux-intc,
9  address and length means one register. Since address of mux-intc is in the
10  range of intc. mux-intc is secondary interrupt controller.
11- reg-names : Name of the register set of the interrupt controller. It's
12  only required in mux-intc interrupt controller.
13- interrupts : Should be the port interrupt shared by mux interrupts. It's
14  only required in mux-intc interrupt controller.
15- interrupt-controller : Identifies the node as an interrupt controller.
16- #interrupt-cells : Specifies the number of cells needed to encode an
17  interrupt source.
18- mrvl,intc-nr-irqs : Specifies the number of interrupts in the interrupt
19  controller.
20- mrvl,clr-mfp-irq : Specifies the interrupt that needs to clear MFP edge
21  detection first.

23Example:
24	intc: interrupt-controller@d4282000 {
25		compatible = "mrvl,mmp2-intc";
26		interrupt-controller;
27		#interrupt-cells = <1>;
28		reg = <0xd4282000 0x1000>;
29		mrvl,intc-nr-irqs = <64>;
30	};
31
32	intcmux4@d4282150 {
33		compatible = "mrvl,mmp2-mux-intc";
34		interrupts = <4>;
35		interrupt-controller;
36		#interrupt-cells = <1>;
37		reg = <0x150 0x4>, <0x168 0x4>;
38		reg-names = "mux status", "mux mask";
39		mrvl,intc-nr-irqs = <2>;
40	};
41
42* Marvell Orion Interrupt controller
43
44Required properties
45- compatible :  Should be "marvell,orion-intc".
46- #interrupt-cells: Specifies the number of cells needed to encode an
47  interrupt source. Supported value is <1>.
48- interrupt-controller : Declare this node to be an interrupt controller.
49- reg : Interrupt mask address. A list of 4 byte ranges, one per controller.
50        One entry in the list represents 32 interrupts.
51
52Example:
53
54	intc: interrupt-controller {
55        	compatible = "marvell,orion-intc", "marvell,intc";
56		interrupt-controller;
57		#interrupt-cells = <1>;
58                reg = <0xfed20204 0x04>,
59		      <0xfed20214 0x04>;
60        };
