     Marvell Armada 370, 375, 38x, XP Interrupt Controller
     -----------------------------------------------------
     
     Required properties:
     - compatible: Should be "marvell,mpic"
     - interrupt-controller: Identifies the node as an interrupt controller.
     - msi-controller: Identifies the node as an PCI Message Signaled
       Interrupt controller.
     - #interrupt-cells: The number of cells to define the interrupts. Should be 1.
      The cell is the IRQ number
    
    - reg: Should contain PMIC registers location and length. First pair
      for the main interrupt registers, second pair for the per-CPU
      interrupt registers. For this last pair, to be compliant with SMP
      support, the "virtual" must be use (For the record, these registers
      automatically map to the interrupt controller registers of the
      current CPU)
    
    Optional properties:
    
    - interrupts: If defined, then it indicates that this MPIC is
      connected as a slave to another interrupt controller. This is
      typically the case on Armada 375 and Armada 38x, where the MPIC is
      connected as a slave to the Cortex-A9 GIC. The provided interrupt
      indicate to which GIC interrupt the MPIC output is connected.
    
    Example:
    
            mpic: interrupt-controller@d0020000 {
                  compatible = "marvell,mpic";
                  #interrupt-cells = <1>;
                  #address-cells = <1>;
                  #size-cells = <1>;
                  interrupt-controller;
                  msi-controller;
                  reg = <0xd0020a00 0x1d0>,
                        <0xd0021070 0x58>;
            };
