+* Milbeaut AXI DMA Controller
+
+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>;
+ };
