1 * Marvell MMP Interrupt controller
4 - compatible : Should be
5 "mrvl,mmp-intc" on Marvel MMP,
6 "mrvl,mmp2-intc" along with "mrvl,mmp2-mux-intc" on MMP2 or
7 "marvell,mmp3-intc" with "mrvl,mmp2-mux-intc" on MMP3
8 - reg : Address and length of the register set of the interrupt controller.
9 If the interrupt controller is intc, address and length means the range
10 of the whole interrupt controller. The "marvell,mmp3-intc" controller
11 also has a secondary range for the second CPU core. If the interrupt
12 controller is mux-intc, address and length means one register. Since
13 address of mux-intc is in the range of intc. mux-intc is secondary
15 - reg-names : Name of the register set of the interrupt controller. It's
16 only required in mux-intc interrupt controller.
17 - interrupts : Should be the port interrupt shared by mux interrupts. It's
18 only required in mux-intc interrupt controller.
19 - interrupt-controller : Identifies the node as an interrupt controller.
20 - #interrupt-cells : Specifies the number of cells needed to encode an
22 - mrvl,intc-nr-irqs : Specifies the number of interrupts in the interrupt
24 - mrvl,clr-mfp-irq : Specifies the interrupt that needs to clear MFP edge

46 * Marvell Orion Interrupt controller
49 - compatible : Should be "marvell,orion-intc".
50 - #interrupt-cells: Specifies the number of cells needed to encode an
51 interrupt source. Supported value is <1>.
52 - interrupt-controller : Declare this node to be an interrupt controller.
53 - reg : Interrupt mask address. A list of 4 byte ranges, one per controller.
54 One entry in the list represents 32 interrupts.
