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
