[PATCH 3/3][V2] dmaengine: axi-dmac: assign `copy_align` property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The `copy_align` property is a generic property that describes alignment
for DMA memcpy & sg ops.
It serves mostly an informational purpose, and can be used in DMA tests, to
pass the info to know what alignment to expect.
