Merge tag 'dmaengine-4.16-rc1' of git://git.infradead.org/users/vkoul/slave-dma

Pull dmaengine updates from Vinod Koul:
 "This time is smallish update with updates mainly to drivers:

   - updates to xilinx and zynqmp dma controllers

   - update reside calculation for rcar controller

   - more RSTify fixes for documentation

   - add support for race free transfer termination and updating for
     users for that

   - support for new rev of hidma with addition new APIs to get device
     match data in ACPI/OF

   - random updates to bunch of other drivers"
