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
