Hi Linus, Here is the pull request for dmaengine. Please pull to receive update mostly on the drivers. Please note, as reported by SFR, we have a merge conflict in dmatest, the fix is already in linux-next. Since, you like to see and resolve conflicts yourself, I have left it for you. The following changes since commit bfeffd155283772bbe78c6a05dec7c0128ee500c: Linux 5.0-rc1 (2019-01-06 17:08:20 -0800) are available in the Git repository at: git://git.infradead.org/users/vkoul/slave-dma.git tags/dmaengine-5.1-rc1 for you to fetch changes up to feb59d77a46d5df93864471ca926b6701479091b: Merge branch 'topic/xilinx' into for-linus (2019-03-12 12:05:47 +0530) ---------------------------------------------------------------- dmaengine updates for v5.1-rc1 - dmatest updates for modularizing common struct and code - remove SG support for VDMA xilinx IP and updates to driver - Update to dw driver to support Intel iDMA controllers multi-block support - tegra updates for proper reporting of residue - Add Snow Ridge ioatdma device id and support for IOATDMA v3.4 - struct_size() usage and useless LIST_HEAD cleanups in subsystem. - qDMA controller driver for Layerscape SoCs - stm32-dma PM Runtime support - And usual updates to imx-sdma, sprd, Documentation, fsl-edma, bcm2835, qcom_hidma etc ---------------------------------------------------------------- Aditya Pakki (3): dmaengine: mv_xor: Fix a missing check in mv_xor_channel_add dmaengine: qcom_hidma: Check for driver register failure dmaengine: stm32-mdma: Add a check on read_u32_array Alexandru Ardelean (3): dmaengine: dmatest: wrap src & dst data into a struct dmaengine: dmatest: add short-hand `buf_size` var in dmatest_func() dmaengine: dmatest: move test data alloc & free into functions Anders Roxell (1): dmaengine: imx-dma: fix warning comparison of distinct pointer types Andrea Merello (6): dmaengine: xilinx_dma: commonize DMA copy size calculation dmaengine: xilinx_dma: in axidma slave_sg and dma_cyclic mode align split descriptors dt-bindings: dmaengine: xilinx_dma: add optional xlnx,sg-length-width property dmaengine: xilinx_dma: autodetect whether the HW supports scatter-gather dt-bindings: dmaengine: xilinx_dma: drop include-sg property dmaengine: xilinx_dma: Drop SG support for VDMA IP Andy Duan (1): dmaengine: imx-sdma: pass ->dev to dma_alloc_coherent() API Andy Shevchenko (8): dmaengine: dw: Add missed multi-block support for iDMA 32-bit dmaengine: dw: Remove misleading is_private property dmaengine: dw: Remove unused internal property dmaengine: dw: Split DW and iDMA 32-bit operations dmaengine: dw: Reset DRAIN bit when resume the channel dmaengine: dw: Don't pollute CTL_LO on iDMA 32-bit dmaengine: dw: convert to SPDX identifiers dmaengine: dw-axi-dmac: Fix trivia typo Angus Ainslie (Purism) (3): dmaengine: imx-sdma: add clock ratio 1:1 check dmaengine: imx-sdma: add a test for imx8mq multi sdma devices dmaengine: imx-sdma: fix consistent dma test failures Arnd Bergmann (1): dmaengine: fsl-qdma: add MODULE_LICENSE Baolin Wang (2): dt-bindings: dmaengine: sprd: Change channel id to slave id for DMA cell specifier dmaengine: sprd: Change channel id to slave id for DMA cell specifier Ben Dooks (5): dmaengine: tegra: avoid overflow of byte tracking dmaengine: tegra: make byte counters unsigned int dmaengine: tegra: fix incorrect case of DMA dmaengine: tegra: reduce channel name field size dmaengine: tegra: add tracepoints to driver Dave Jiang (4): dmaengine: ioatdma: Add Snow Ridge ioatdma device id dmaengine: ioatdma: disable DCA enabling on IOATDMA v3.4 dmaengine: ioatdma: add descriptor pre-fetch support for v3.4 dmaengine: ioatdma: support latency tolerance report (LTR) for v3.4 Federico Vaga (1): Documentation :dmaengine: clarify DMA desc. pointer after submission Gustavo A.
