Merge tag 'dmaengine-4.20-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul:
- Support for ColdFire mcf5441x edma controller
- Support for link list mode in sprd dma
- More users of managed dmaenginem_async_device_register API
- Cyclic mode support in owl dma driver
- DT updates for renesas drivers, dma-jz4780 updates and support for
JZ4770, JZ4740 and JZ4725B controllers
- Removal of deprecated dma_slave_config direction in dmaengine
drivers, few more users will be removed in next cycle and eventually
removed.
- Minor updates to idma64, ioat, pxa, ppc drivers
