| 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 | }; |
