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 ]
