Merge tag 'dmaengine-4.13-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul: - removal of AVR32 support in dw driver as AVR32 is gone - new driver for Broadcom stream buffer accelerator (SBA) RAID driver - add support for Faraday Technology FTDMAC020 in amba-pl08x driver - IOMMU support in pl330 driver - updates to bunch of drivers * tag 'dmaengine-4.13-rc1' of git://git.infradead.org/users/vkoul/slave-dma: (36 commits) dmaengine: qcom_hidma: correct API violation for submit dmaengine: zynqmp_dma: Remove max len check in zynqmp_dma_prep_memcpy dmaengine: tegra-apb: Really fix runtime-pm usage dmaengine: fsl_raid: make of_device_ids const. dmaengine: qcom_hidma: allow ACPI/DT parameters to be overridden dmaengine: fsldma: set BWC, DAHTS and SAHTS values correctly dmaengine: Kconfig: Simplify the help text for MXS_DMA dmaengine: pl330: Delete unused functions dmaengine: Replace WARN_TAINT_ONCE() with pr_warn_once() dmaengine: Kconfig: Extend the dependency for MXS_DMA dmaengine: mxs: Use %zu for printing a size_t variable dmaengine: ste_dma40: Cleanup scatterlist layering violations dmaengine: imx-dma: cleanup scatterlist layering violations dmaengine: use proper name for the R-Car SoC dmaengine: imx-sdma: Fix compilation warning. dmaengine: imx-sdma: Handle return value of clk_prepare_enable dmaengine: pl330: Add IOMMU support to slave tranfers dmaengine: DW DMAC: Handle return value of clk_prepare_enable dmaengine: pl08x: use GENMASK() to create bitmasks dmaengine: pl08x: Add support for Faraday Technology FTDMAC020 ...
