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"
