Merge tag 'dmaengine-4.5-rc1' of git://git.infradead.org/users/vkoul/slave-dma

Pull dmaengine updates from Vinod Koul:
 "This round we have few new features, new driver and updates to few
  drivers.

  The new features to dmaengine core are:
   - Synchronized transfer termination API to terminate the dmaengine
     transfers in synchronized and async fashion as required by users.
     We have its user now in ALSA dmaengine lib, img, at_xdma, axi_dmac
     drivers.
   - Universal API for channel request and start consolidation of
     request flows.  It's user is ompa-dma driver.
   - Introduce reuse of descriptors and use in pxa_dma driver

  Add/Remove:
   - New STM32 DMA driver
   - Removal of unused R-Car HPB-DMAC driver

  Updates:
   - ti-dma-crossbar updates for supporting eDMA
   - tegra-apb pm updates
   - idma64
   - mv_xor updates
   - ste_dma updates"
