.SH "DESCRIPTION"
.PP
Initializes the {dst,src}_addr, {dst,src}_maxburst, {dst,src}_addr_width and slave_id fields of the DMA slave config from the same fields of the DAI DMA data struct\&. The src and dst fields will be initialized depending on the direction of the substream\&. If the substream is a playback stream the dst fields will be initialized, if it is a capture stream the src fields will be initialized\&. The {dst,src}_addr_width field will only be initialized if the SND_DMAENGINE_PCM_DAI_FLAG_PACK flag is set or if the addr_width field of the DAI DMA data struct is not equal to DMA_SLAVE_BUSWIDTH_UNDEFINED\&. If both conditions are met the latter takes priority\&.
