Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma
* 'next' of git://git.infradead.org/users/vkoul/slave-dma: (53 commits) ARM: mach-shmobile: specify CHCLR registers on SH7372 dma: shdma: fix runtime PM: clear channel buffers on reset dma/imx-sdma: save irq flags when use spin_lock in sdma_tx_submit dmaengine/ste_dma40: clear LNK on channel startup dmaengine: intel_mid_dma: remove legacy pm interface ASoC: mxs: correct 'direction' of device_prep_dma_cyclic dmaengine: intel_mid_dma: error path fix dmaengine: intel_mid_dma: locking and freeing fixes mtd: gpmi-nand: move to dma_transfer_direction mtd: fix compile error for gpmi-nand mmc: mxs-mmc: fix the dma_transfer_direction migration dmaengine: add DMA_TRANS_NONE to dma_transfer_direction dma: mxs-dma: Don't use CLKGATE bits in CTRL0 to disable DMA channels dma: mxs-dma: make mxs_dma_prep_slave_sg() multi user safe dma: mxs-dma: Always leave mxs_dma_init() with the clock disabled. dma: mxs-dma: fix a typo in comment DMA: PL330: Remove pm_runtime_xxx calls from pl330 probe/remove video i.MX IPU: Fix display connections i.MX IPU DMA: Fix wrong burstsize settings dmaengine/ste_dma40: allow fixed physical channel ... Fix up conflicts in drivers/dma/{Kconfig,mxs-dma.c,pl330.c} The conflicts looked pretty trivial, but I'll ask people to verify them.
