Merge tag 'dmaengine-4.5-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul: "This round we have few new features, new driver and updates to few drivers. The new features to dmaengine core are: - Synchronized transfer termination API to terminate the dmaengine transfers in synchronized and async fashion as required by users. We have its user now in ALSA dmaengine lib, img, at_xdma, axi_dmac drivers. - Universal API for channel request and start consolidation of request flows. It's user is ompa-dma driver. - Introduce reuse of descriptors and use in pxa_dma driver Add/Remove: - New STM32 DMA driver - Removal of unused R-Car HPB-DMAC driver Updates: - ti-dma-crossbar updates for supporting eDMA - tegra-apb pm updates - idma64 - mv_xor updates - ste_dma updates" * tag 'dmaengine-4.5-rc1' of git://git.infradead.org/users/vkoul/slave-dma: (54 commits) dmaengine: mv_xor: add suspend/resume support dmaengine: mv_xor: de-duplicate mv_chan_set_mode*() dmaengine: mv_xor: remove mv_xor_chan->current_type field dmaengine: omap-dma: Add support for DMA filter mapping to slave devices dmaengine: edma: Add support for DMA filter mapping to slave devices dmaengine: core: Introduce new, universal API to request a channel dmaengine: core: Move and merge the code paths using private_candidate dmaengine: core: Skip mask matching when it is not provided to private_candidate dmaengine: mdc: Correct terminate_all handling dmaengine: edma: Add probe callback to edma_tptc_driver dmaengine: dw: fix potential memory leak in dw_dma_parse_dt() dmaengine: stm32-dma: Fix unchecked deference of chan->desc dmaengine: sh: Remove unused R-Car HPB-DMAC driver dmaengine: usb-dmac: Document SoC specific compatibility strings ste_dma40: Delete an unnecessary variable initialisation in d40_probe() ste_dma40: Delete another unnecessary check in d40_probe() ste_dma40: Delete an unnecessary check before the function call "kmem_cache_destroy" dmaengine: tegra-apb: Free interrupts before killing tasklets dmaengine: tegra-apb: Update driver to use GFP_NOWAIT dmaengine: tegra-apb: Only save channel state for those in use ...
