[V2 PATCH] 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.

Changelog v1 -> v2:
* re-applied & moved the `copy_align` assignment; apparently it was
  conflicting with another patch from another series
