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

Pull slave-dmaengine update from Vinod Koul:
 "This time we have a new dmaengine driver from the tegra folks.  Also
  we have Guennadi's cleanup of sh drivers which incudes a library for
  sh drivers.  And the usual odd fixes in bunch of drivers and some nice
  cleanup of dw_dmac from Andy."

Fix up conflicts in drivers/mmc/host/sh_mmcif.c

* 'next' of git://git.infradead.org/users/vkoul/slave-dma: (46 commits)
  dmaengine: Cleanup logging messages
  mmc: sh_mmcif: switch to the new DMA channel allocation and configuration

  ASoC: siu: don't use DMA device for channel filtering
  dmaengine: shdma: (cosmetic) simplify a static function
  dmaengine: at_hdmac: add a few const qualifiers
  dw_dmac: use 'u32' for LLI structure members, not dma_addr_t
  dw_dmac: mark dwc_dump_lli inline
