Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma

Pull slave-dmaengine updates from Vinod Koul:
 "This time we have Andy updates on dw_dmac which is attempting to make
  this IP block available as PCI and platform device though not fully
  complete this time.

  We also have TI EDMA moving the dma driver to use dmaengine APIs, also
  have a new driver for mmp-tdma, along with bunch of small updates.

  Now for your excitement the merge is little unusual here, while
  merging the auto merge on linux-next picks wrong choice for pl330
  (drivers/dma/pl330.c) and this causes build failure.  The correct
  resolution is in linux-next.  (DMA: PL330: Fix build error) I didn't
  back merge your tree this time as you are better than me so no point
  in doing that for me :)"

Fixed the pl330 conflict as in linux-next, along with trivial header
file conflicts due to changed includes.
