+* Marvell XOR v2 engines
+
+Required properties:
+- compatible: one of the following values:
+ "marvell,armada-7k-xor"
+ "marvell,xor-v2"
+- reg: Should contain registers location and length (two sets)
+ the first set is the DMA registers
+ the second set is the global registers
+- msi-parent: Phandle to the MSI-capable interrupt controller used for
+ interrupts.
+
+Optional properties:
+- clocks: Optional reference to the clock used by the XOR engine.
+
+Example:
+
+ xor0@400000 {
+ compatible = "marvell,xor-v2";
+ reg = <0x400000 0x1000>,
+ <0x410000 0x1000>;
+ msi-parent = <&gic_v2m0>;
+ dma-coherent;
+ };
