   15   Platform DMA is a DMA engine of SiFive Unleashed. It supports 4
   16   channels. Each channel has 2 interrupts. One is for DMA done and
   17   the other is for DME error.
   18 
   19   In different SoC, DMA could be attached to different IRQ line.
   20   DT file need to be changed to meet the difference. For technical
   21   doc,
