Hello,

Here is a v3 of the series making some fixes and improvements to the
mv_xor driver.

Changes v2 -> v3:

 * Added Reviewed-by from Maxime Ripard on patches 1, 3, 4 and 5.

 * Added an additional patch improving the performance of the XOR
   engine by only using a subset of the available channels depending
   on the number of CPUs in the system.

Changes v1 -> v2:

 * Device Tree related changes omitted, since they have been applied
   by one of the ARM mach-mvebu maintainer.

 * Addition of one commit, "dmaengine: mv_xor: fix big endian
   operation in register mode", fixing a regression introduced by one
   the patches currently in the 'next' branch of Vinod's
   repository. It should be merged as part of 4.2.

 * Addition of two cleanup patches:

    dmaengine: mv_xor: remove mv_xor_chan->current_type field
    dmaengine: mv_xor: de-duplicate mv_chan_set_mode*()

   These patches, like the two other non-fixes, can either go in 4.2
   if it's not too late, or in 4.3.

Thanks,

Thomas
