- 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

you can enable the config. The DMA engine can only be used
|

with MediaTek SoCs.
