Pull dmaengine updates from Vinod Koul:
"This update brings:
- the big cleanup up by Maxime for device control and slave
capabilities. This makes the API much cleaner.
- new IMG MDC driver by Andrew
- new Renesas R-Car Gen2 DMA Controller driver by Laurent along with
bunch of fixes on rcar drivers
- odd fixes and updates spread over driver"

RAID operations in the MD driver. This menu only presents
