Merge tag 'dmaengine-5.4-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul: - Move Dmaengine DT bindings to YAML and convert Allwinner to schema. - FSL dma device_synchronize implementation - DW split acpi and of helpers and updates to driver and support for Elkhart Lake - Move filter fn as private for omap-dma and edma drivers and improvements to these drivers - Mark expected switch fall-through in couple of drivers - Renames of shdma and nbpfaxi binding document - Minor updates to bunch of drivers * tag 'dmaengine-5.4-rc1' of git://git.infradead.org/users/vkoul/slave-dma: (55 commits) dmaengine: ti: edma: Use bitmap_set() instead of open coded edma_set_bits() dmaengine: ti: edma: Only reset region0 access registers dmaengine: ti: edma: Do not reset reserved paRAM slots dmaengine: iop-adma.c: fix printk format warning dmaengine: stm32-dma: Use struct_size() helper dt-bindings: dmaengine: dma-common: Fix the dma-channel-mask property dmanegine: ioat/dca: Use struct_size() helper dmaengine: iop-adma: remove set but not used variable 'slots_per_op' dmaengine: dmatest: Add support for completion polling dmaengine: ti: omap-dma: Remove variable override in omap_dma_tx_status() dmaengine: ti: omap-dma: Remove 'Assignment in if condition' dmaengine: ti: edma: Remove 'Assignment in if condition' dmaengine: dw: platform: Split OF helpers to separate module dmaengine: dw: platform: Split ACPI helpers to separate module dmaengine: dw: platform: Move handle check to dw_dma_acpi_controller_register() dmaengine: dw: platform: Switch to acpi_dma_controller_register() dmaengine: dw: platform: Use devm_platform_ioremap_resource() dmaengine: dw: platform: Enable iDMA 32-bit on Intel Elkhart Lake dmaengine: dw: platform: Use struct dw_dma_chip_pdata dmaengine: dw: Export struct dw_dma_chip_pdata for wider use ...
