Mainly follows DMAengine controller doc[1] to implement and take other DMA drivers as reference. Such as - drivers/dma/fsl-edma.c - drivers/dma/dw-edma/ - drivers/dma/pxa-dma.c Using DMA test client[2] to test. Detailed datasheet is doc[3]. Driver supports: - 4 physical DMA channels, share same DONE and error interrupt handler. - Support MEM_TO_MEM - Tested by DMA test client - patches include DT Bindgins document and dts for fu450-c000 SoC. Separate dts patch for easier review and apply to different branch or SoC platform. - retry 1 time if DMA error occurs.
