Detailed Description

struct d40_desc - A descriptor is one DMA job.

: LLI settings for physical channel. Both src and dst= points into the lli_pool, to base if lli_len > 1 or to pre_alloc_lli if lli_len equals one. : Same as above but for logical channels. : The pool with two entries pre-allocated. : Number of llis of current descriptor. : Number of transferred llis. : Number of LCLA entries allocated. : DMA engine struct. Used for among other things for communication during a transfer. : List entry. : true if the client owns this descriptor. : true if this is a cyclic job

This descriptor is used for both logical and physical transfers.
