1 Marvell Armada 370, 375, 38x, XP Interrupt Controller
2 -----------------------------------------------------
5 - compatible: Should be "marvell,mpic"
6 - interrupt-controller: Identifies the node as an interrupt controller.
7 - msi-controller: Identifies the node as an PCI Message Signaled
9 - #interrupt-cells: The number of cells to define the interrupts. Should be 1.
10 The cell is the IRQ number
12 - reg: Should contain PMIC registers location and length. First pair
13 for the main interrupt registers, second pair for the per-CPU
14 interrupt registers. For this last pair, to be compliant with SMP
15 support, the "virtual" must be use (For the record, these registers
16 automatically map to the interrupt controller registers of the
21 - interrupts: If defined, then it indicates that this MPIC is
22 connected as a slave to another interrupt controller. This is
23 typically the case on Armada 375 and Armada 38x, where the MPIC is
24 connected as a slave to the Cortex-A9 GIC. The provided interrupt
25 indicate to which GIC interrupt the MPIC output is connected.
