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
