Hi,

The customer wants to use DMA to move data, but the DMA applied for using the kernel's EDMA is SDMA by default. How do I specify the EDMA?
At present, trying to specify in the device tree has no effect, and the applied DMA does not work properly.
In addition, check the DMA ENGINE framework of the kernel and find that there is no specified API for the DMA. The DMA directly applied for by the dma_request_channel is SDMA.
