+Marvell Armada 370 and Armada XP Interrupt Controller
+-----------------------------------------------------
+
+Required properties:
+- compatible: Should be "marvell,mpic"
+- interrupt-controller: Identifies the node as an 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
+
+Example:
+
+ mpic: interrupt-controller@d0020000 {
+ compatible = "marvell,mpic";
+ #interrupt-cells = <1>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ interrupt-controller;
+ reg = <0xd0020000 0x1000>,
+ <0xd0021000 0x1000>;
+ };

+Marvell Armada 370 and Armada XP Global Timers
+----------------------------------------------
+
+Required properties:
+- compatible: Should be "marvell,armada-370-xp-timer"
+- interrupts: Should contain the list of Global Timer interrupts
+- reg: Should contain the base address of the Global Timer registers
+
+Optional properties:
+- marvell,timer-25Mhz: Tells whether the Global timer supports the 25
+ Mhz fixed mode (available on Armada XP and not on Armada 370)

+compatible: must contain "marvell,armada370"
+
+In addition, boards using the Marvell Armada XP SoC shall have the
+following property:
+
+Required root node property:
+
