Merge tag 'dmaengine-4.21-rc1' of git://git.infradead.org/users/vkoul/slave-dma

Pull dmaengine updates from Vinod Koul:
 "This includes a new driver, removes R-Mobile APE6 as it is no longer
  used, sprd cyclic dma support, last batch of dma_slave_config
  direction removal and random updates to bunch of drivers.

  Summary:
   - New driver for UniPhier MIO DMA controller
   - Remove R-Mobile APE6 support
   - Sprd driver updates and support for cyclic link-list
   - Remove dma_slave_config direction usage from rest of drivers
   - Minor updates to dmatest, dw-dmac, zynqmp and bcm dma drivers"
