Merge tag 'dmaengine-4.10-rc1' of git://git.infradead.org/users/vkoul/slave-dma

Pull dmaengine updates from Vinod Koul:
 "Fairly routine update this time around with all changes specific to
  drivers:

   - New driver for STMicroelectronics FDMA
   - Memory-to-memory transfers on dw dmac
   - Support for slave maps on pl08x devices
   - Bunch of driver fixes to use dma_pool_zalloc
   - Bunch of compile and warning fixes spread across drivers"

[ The ST FDMA driver already came in earlier through the remoteproc tree ]
