+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.
+ mpic: interrupt-controller@d0020000 {
+ compatible = "marvell,mpic";
+ #interrupt-cells = <1>;
+ #address-cells = <1>;
+ #size-cells = <1>;

+ reg = <0xd0020a00 0x1d0>,
