Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma

Pull slave-dmaengine updates from Vinod Koul:
 "Nothing exciting this time, odd fixes in a bunch of drivers"

* 'next' of git://git.infradead.org/users/vkoul/slave-dma:
  dmaengine: at_hdmac: take maxburst from slave configuration
  dmaengine: at_hdmac: remove ATC_DEFAULT_CTRLA constant
  dmaengine: at_hdmac: remove some at_dma_slave comments
  dma: imx-sdma: make channel0 operations atomic
  dmaengine: Fixup dmaengine_prep_slave_single() to be actually useful
  dmaengine: Use dma_sg_len(sg) instead of sg->length
  dmaengine: Use sg_dma_address instead of sg_phys
  DMA: PL330: Remove duplicate header file inclusion
  dma: imx-sdma: keep the callbacks invoked in the tasklet
  dmaengine: dw_dma: add Device Tree probing capability
  dmaengine: dw_dmac: Add clk_{un}prepare() support
  dma/amba-pl08x: add support for the Nomadik variant
  dma/amba-pl08x: check for terminal count status only
