*	dmaengine: Add an enum for the dmaengine alignment constraints	Maxime Ripard	2015-08-05	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Most drivers need to set constraints on the buffer alignment for async tx operations. However, even though it is documented, some drivers either use a defined constant that is not matching what the alignment variable expects (like DMA_BUSWIDTH_* constants) or fill the alignment in bytes instead of power of two. Add a new enum for these alignments that matches what the framework expects, and convert the drivers to it.

*	dma: MIC X100 DMA Driver	Siva Yerramreddy	2014-07-12	1	-0/+286
	This patch implements DMA Engine API for DMA controller on MIC X100 Coprocessors. DMA h/w is shared between host and card s/w. Channels 0 to 3 are used by host and 4 to 7 are used by card. Since the DMA device doesn't show up as PCIe device, a virtual bus called mic bus is created and virtual devices are added on that bus to follow device model. Allowed dma transfer directions are host to card, card to host and card to card.
