Merge tag 'dmaengine-4.4-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul:
"This time we have a very typical update which is mostly fixes and
updates to drivers and no new drivers.
- the biggest change is coming from Peter for edma cleanup which even
caused some last minute regression, things seem settled now
- idma64 and dw updates
- iotdma updates
- module autoload fixes for various drivers
- scatter gather support for hdmac"
