Merge tag 'dmaengine-4.19-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull DMAengine updates from Vinod Koul:
"This round brings couple of framework changes, a new driver and usual
driver updates:
- new managed helper for dmaengine framework registration
- split dmaengine pause capability to pause and resume and allow
drivers to report that individually
- update dma_request_chan_by_mask() to handle deferred probing
- move imx-sdma to use virt-dma
- new driver for Actions Semi Owl family S900 controller
- minor updates to intel, renesas, mv_xor, pl330 etc"
