Cover letter [PATCHv2 0/2] dma: mv_xor: big endian support
Quoted 6 lines · Thomas Petazzoni

Vinod, Dan,

I've sent the below two patches about three weeks ago, and they haven't received any comments. They are relatively simple, so would it be possible to queue them for 3.12 ?

Jason, Andrew, Gregory, as the Marvell EBU maintainers, it would be great if you could give your Acked-by and/or Tested-by on those patches.

Thanks!

Vinod, Dan,

This small set of patches adds support for big endian operation in the DMA mv_xor driver. It has been tested in both little-endian and big-endian modes on the Armada XP GP board.

If possible, I'd like those to be merged for 3.12.

These look fine to me.

Dan let me know if you okay with me to carry these

Changes since v1:
* Use readl_relaxed() and writel_relaxed() instead of readl/writel when converting from raw_readl/raw_writel, since they preserve the same barrier behavior. Suggested by Russell King.

Thanks!

Thomas

Thomas Petazzoni (2):
mv_xor: use {readl,writel}_relaxed instead of __raw_{readl,writel}
mv_xor: support big endian systems using descriptor swap feature
