^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) Required property:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) - compatible: Should be "socionext,milbeaut-m10v-xdmac"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) - reg: Should contain DMA registers location and length.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) - interrupts: Should contain all of the per-channel DMA interrupts.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) Number of channels is configurable - 2, 4 or 8, so
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) the number of interrupts specified should be {2,4,8}.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) - #dma-cells: Should be 1.
