    1 * Milbeaut AXI DMA Controller
    2 
    3 Milbeaut AXI DMA controller has only memory to memory transfer capability.
    4 
    5 * DMA controller
    6 
    7 Required property:
    8 - compatible:   Should be  "socionext,milbeaut-m10v-xdmac"
    9 - reg:          Should contain DMA registers location and length.
   10 - interrupts:   Should contain all of the per-channel DMA interrupts.
   11                 Number of channels is configurable - 2, 4 or 8, so
   12                 the number of interrupts specified should be {2,4,8}.
   13 - #dma-cells:   Should be 1.
   14 
   15 Example:
   16         xdmac0: dma-controller@1c250000 {
   17                 compatible = "socionext,milbeaut-m10v-xdmac";
   18                 reg = <0x1c250000 0x1000>;
   19                 interrupts = <0 17 0x4>,
   20                              <0 18 0x4>,
   21                              <0 19 0x4>,
   22                              <0 20 0x4>;
   23                 #dma-cells = <1>;
   24         };
