* 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.
Number of channels is configurable - 2, 4 or 8, so
the number of interrupts specified should be {2,4,8}.
- #dma-cells: Should be 1.
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>;
};
