Merge tag 'dmaengine-4.16-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul: "This time is smallish update with updates mainly to drivers: - updates to xilinx and zynqmp dma controllers - update reside calculation for rcar controller - more RSTify fixes for documentation - add support for race free transfer termination and updating for users for that - support for new rev of hidma with addition new APIs to get device match data in ACPI/OF - random updates to bunch of other drivers" * tag 'dmaengine-4.16-rc1' of git://git.infradead.org/users/vkoul/slave-dma: (47 commits) dmaengine: dmatest: fix container_of member in dmatest_callback dmaengine: stm32-dmamux: Remove unnecessary platform_get_resource() error check dmaengine: sprd: statify 'sprd_dma_prep_dma_memcpy' dmaengine: qcom_hidma: simplify DT resource parsing dmaengine: xilinx_dma: Free BD consistent memory dmaengine: xilinx_dma: Fix warning variable prev set but not used dmaengine: xilinx_dma: properly configure the SG mode bit in the driver for cdma dmaengine: doc: format struct fields using monospace dmaengine: doc: fix bullet list formatting dmaengine: ti-dma-crossbar: Fix event mapping for TPCC_EVT_MUX_60_63 dmaengine: cppi41: Fix channel queues array size check dmaengine: imx-sdma: Add MODULE_FIRMWARE dmaengine: xilinx_dma: Fix typos dmaengine: xilinx_dma: Differentiate probe based on the ip type dmaengine: xilinx_dma: fix style issues from checkpatch dmaengine: xilinx_dma: Fix kernel doc warnings dmaengine: xilinx_dma: Fix race condition in the driver for multiple descriptor scenario dmaeninge: xilinx_dma: Fix bug in multiple frame stores scenario in vdma dmaengine: xilinx_dma: Check for channel idle state before submitting dma descriptor dmaengine: zynqmp_dma: Fix race condition in the probe ...
