Merge tag 'dmaengine-4.14-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul:
"This one features the usual updates to the drivers and one good part
of removing DA_SG from core as it has no users.
Summary:
- Remove DMA_SG support as we have no users for this feature
- New driver for Altera / Intel mSGDMA IP core
- Support for memset in dmatest and qcom_hidma driver
- Update for non cyclic mode in k3dma, bunch of update in bam_dma,
bcm sba-raid
- Constify device ids across drivers"
