1* Milbeaut AHB DMA Controller
2
3Milbeaut AHB DMA controller has transfer capability below.
4 - device to memory transfer
5 - memory to device transfer
6
7Required 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.
