[PATCH V5 2/9] device property: Introducing enum dev_dma_attr

From: Suravee Suthikulpanit
Date: Wed Oct 28 2015 - 18:51:30 EST

A device could have one of the following DMA attributes:
* DMA not supported
* DMA non-coherent
* DMA coherent

So, this patch introduces enum dev_dma_attribute. This will be used by
new APIs introduced in later patches.
