+
+Milbeaut AXI DMA controller has only memory to memory transfer capability.
+
+* DMA controller
+
+Required property:
+- compatible: 		Should be  "socionext,milbeaut-m10v-xdmac"
+- reg:			Should contain DMA registers location and length.
+- interrupts: 		Should contain all of the per-channel DMA interrupts.
+- #dma-cells: 		Should be 1.
+- dma-channels: 	Number of DMA channels supported by the controller.
+
+Example:
+	xdmac0: dma-controller@1c250000 {
+		compatible = "socionext,milbeaut-m10v-xdmac";
+		reg = <0x1c250000 0x1000>;
+		interrupts = <0 17 0x4>,
+			     <0 18 0x4>,
+			     <0 19 0x4>,
+			     <0 20 0x4>;
+		#dma-cells = <1>;
+		dma-channels = <4>;
