Following are the changes we have done from the previous v1 posted here: https://lkml.org/lkml/2011/12/22/148
As our ADM Scatter-gather hardware needs -32-bit command configuration parameter apart from -32-bit source address -32-bit destination address -16-bit length
So,we have added new parameter in struct scatterlist to support xfer descriptor specific private data, and for supporting ADM Box mode DMA we added new API and data structure.
Ravi Kumar V (2): dmaengine: Add support for per xfer specific privatedata & box dma msm: DMAEngine: Add DMAEngine driver based on old MSM DMA APIs
