Merge tag 'dmaengine-4.11-rc1' of git://git.infradead.org/users/vkoul/slave-dma
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"
