Merge tag 'dmaengine-4.2-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul: "This time we have support for few new devices, few new features and odd fixes spread thru the subsystem. New devices added: - support for CSRatlas7 dma controller - Allwinner H3(sun8i) controller - TI DMA crossbar driver on DRA7x - new pxa driver New features added: - memset support is bought back now that we have a user in xdmac controller - interleaved transfers support different source and destination strides - supporting DMA routers and configuration thru DT - support for reusing descriptors - xdmac memset and interleaved transfer support - hdmac support for interleaved transfers - omap-dma support for memcpy Others: - Constify platform_device_id - mv_xor fixes and improvements" * tag 'dmaengine-4.2-rc1' of git://git.infradead.org/users/vkoul/slave-dma: (46 commits) dmaengine: xgene: fix file permission dmaengine: fsl-edma: clear pending interrupts on initialization dmaengine: xdmac: Add memset support Documentation: dmaengine: document DMA_CTRL_ACK dmaengine: virt-dma: don't always free descriptor upon completion dmaengine: Revert "drivers/dma: remove unused support for MEMSET operations" dmaengine: hdmac: Implement interleaved transfers dmaengine: Move icg helpers to global header dmaengine: mv_xor: improve descriptors list handling and reduce locking dmaengine: mv_xor: Enlarge descriptor pool size dmaengine: mv_xor: add support for a38x command in descriptor mode dmaengine: mv_xor: Rename function for consistent naming dmaengine: mv_xor: bug fix for racing condition in descriptors cleanup dmaengine: pl330: fix wording in mcbufsz message dmaengine: sirf: add CSRatlas7 SoC support dmaengine: xgene-dma: Fix "incorrect type in assignement" warnings dmaengine: fix kernel-doc documentation dmaengine: pxa_dma: add support for legacy transition dmaengine: pxa_dma: add debug information dmaengine: pxa: add pxa dmaengine driver ...
