   1Marvell Armada 370 and Armada XP Interrupt Controller
   2-----------------------------------------------------
   3
   4Required properties:
   5- compatible: Should be "marvell,mpic"
   6- interrupt-controller: Identifies the node as an interrupt controller.
   7- #interrupt-cells: The number of cells to define the interrupts. Should be 1.
   8  The cell is the IRQ number
   9
  10- reg: Should contain PMIC registers location and length. First pair
  11  for the main interrupt registers, second pair for the per-CPU
  12  interrupt registers. For this last pair, to be compliant with SMP
  13  support, the "virtual" must be use (For the record, these registers
  14  automatically map to the interrupt controller registers of the
  15  current CPU)

  21        mpic: interrupt-controller@d0020000 {
  22              compatible = "marvell,mpic";
  23              #interrupt-cells = <1>;
  24              #address-cells = <1>;
  25              #size-cells = <1>;
  26              interrupt-controller;
  27              reg = <0xd0020a00 0x1d0>,
  28                    <0xd0021070 0x58>;
  29        };
