title: Marvell Armada 370, 375, 38x, 39x, XP Interrupt Controller

maintainers:

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.
