    1 * Milbeaut AHB DMA Controller
    2 
    3 Milbeaut AHB DMA controller has transfer capability below.
    4  - device to memory transfer
    5  - memory to device transfer
    6 
    7 Required property:
    8 - compatible:       Should be  "socionext,milbeaut-m10v-hdmac"
    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. Specify the ID of the slave.
   14 - clocks:           Phandle to the clock used by the HDMAC module.
   15

   17 Example:
   18 
   19         hdmac1: dma-controller@1e110000 {
   20                 compatible = "socionext,milbeaut-m10v-hdmac";
   21                 reg = <0x1e110000 0x10000>;
   22                 interrupts = <0 132 4>,
   23                              <0 133 4>,
   24                              <0 134 4>,
   25                              <0 135 4>,
   26                              <0 136 4>,
   27                              <0 137 4>,
   28                              <0 138 4>,
   29                              <0 139 4>;
   30                 #dma-cells = <1>;
   31                 clocks = <&dummy_clk>;
   32         };
