1*4882a593Smuzhiyun* Milbeaut AXI DMA Controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunMilbeaut AXI DMA controller has only memory to memory transfer capability.

5*4882a593Smuzhiyun* DMA controller
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunRequired property:
8*4882a593Smuzhiyun- compatible: 	Should be  "socionext,milbeaut-m10v-xdmac"
9*4882a593Smuzhiyun- reg:		Should contain DMA registers location and length.
10*4882a593Smuzhiyun- interrupts: 	Should contain all of the per-channel DMA interrupts.
11*4882a593Smuzhiyun                Number of channels is configurable - 2, 4 or 8, so
12*4882a593Smuzhiyun                the number of interrupts specified should be {2,4,8}.
13*4882a593Smuzhiyun- #dma-cells: 	Should be 1.
