Pull dmaengine updates from Vinod Koul:
 "This time we fairly boring and bit small update.

   - Support for Intel iDMA 32-bit hardware
   - deprecate broken support for channel switching in async_tx
   - bunch of updates on stm32-dma
   - Cyclic support for zx dma and making in generic zx dma driver
   - Small updates to bunch of other drivers"
