Merge tag 'dmaengine-5.1-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul: - 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 * tag 'dmaengine-5.1-rc1' of git://git.infradead.org/users/vkoul/slave-dma: (81 commits) dmaengine: imx-sdma: fix consistent dma test failures dmaengine: imx-sdma: add a test for imx8mq multi sdma devices dmaengine: imx-sdma: add clock ratio 1:1 check dmaengine: dmatest: move test data alloc & free into functions dmaengine: dmatest: add short-hand `buf_size` var in dmatest_func() dmaengine: dmatest: wrap src & dst data into a struct dmaengine: ioatdma: support latency tolerance report (LTR) for v3.4 dmaengine: ioatdma: add descriptor pre-fetch support for v3.4 dmaengine: ioatdma: disable DCA enabling on IOATDMA v3.4 dmaengine: ioatdma: Add Snow Ridge ioatdma device id dmaengine: sprd: Change channel id to slave id for DMA cell specifier dt-bindings: dmaengine: sprd: Change channel id to slave id for DMA cell specifier dmaengine: mv_xor: Use correct device for DMA API Documentation :dmaengine: clarify DMA desc. pointer after submission Documentation: dmaengine: fix dmatest.rst warning dmaengine: k3dma: Add support for dma-channel-mask dmaengine: k3dma: Delete axi_config dmaengine: k3dma: Upgrade k3dma driver to support hisi_asp_dma hardware Documentation: bindings: dma: Add binding for dma-channel-mask Documentation: bindings: k3dma: Extend the k3dma driver binding to support hisi-asp ...
