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>;

        };

description: |

  The top-level interrupt controller on Marvell Armada 370 and XP. On these

  platforms it also provides inter-processor interrupts.



  On Marvell Armada 375, 38x and 39x this controller is wired under ARM GIC.



  Provides MSI handling for the PCIe controllers.
