[Sound-open-firmware] [PATCH] dw-dma: set msize according to different transfer type
by Keyon Jie 15 Dec '17

For memory to memory copy, we don't require user to set msize, and set them to default 3, that is 2^3=8 items for each burst transaction. For copy have peripheral device source/destination, we use the user configured src_msize and dest_msize, which usually be constrained by device hardware/fifos.
