Merge tag 'dmaengine-5.3-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul: - Add support in dmaengine core to do device node checks for DT devices and update bunch of drivers to use that and remove open coding from drivers - New driver/driver support for new hardware, namely: - MediaTek UART APDMA - Freescale i.mx7ulp edma2 - Synopsys eDMA IP core version 0 - Allwinner H6 DMA - Updates to axi-dma and support for interleaved cyclic transfers - Greg's debugfs return value check removals on drivers - Updates to stm32-dma, hsu, dw, pl330, tegra drivers * tag 'dmaengine-5.3-rc1' of git://git.infradead.org/users/vkoul/slave-dma: (68 commits) dmaengine: Revert "dmaengine: fsl-edma: add i.mx7ulp edma2 version support" dmaengine: at_xdmac: check for non-empty xfers_list before invoking callback Documentation: dmaengine: clean up description of dmatest usage dmaengine: tegra210-adma: remove PM_CLK dependency dmaengine: fsl-edma: add i.mx7ulp edma2 version support dt-bindings: dma: fsl-edma: add new i.mx7ulp-edma dmaengine: fsl-edma-common: version check for v2 instead dmaengine: fsl-edma-common: move dmamux register to another single function dmaengine: fsl-edma: add drvdata for fsl-edma dmaengine: Revert "dmaengine: fsl-edma: support little endian for edma driver" dmaengine: rcar-dmac: Reject zero-length slave DMA requests dmaengine: dw: Enable iDMA 32-bit on Intel Elkhart Lake dmaengine: dw-edma: fix semicolon.cocci warnings dmaengine: sh: usb-dmac: Use [] to denote a flexible array member dmaengine: dmatest: timeout value of -1 should specify infinite wait dmaengine: dw: Distinguish ->remove() between DW and iDMA 32-bit dmaengine: fsl-edma: support little endian for edma driver dmaengine: hsu: Revert "set HSU_CH_MTSR to memory width" dmagengine: pl330: add code to get reset property dt-bindings: pl330: document the optional resets property ...
