Subject: [PATCH v2 0/2] Add Qualcomm MSM ADM DMAEngine driver
Newsgroups: gmane.linux.kernel
Date: Friday 6th January 2012 12:47:30 UTC (over 4 years ago)
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.

  dmaengine: Add support for per xfer specific privatedata & box dma
  msm: DMAEngine: Add DMAEngine driver based on old MSM DMA APIs
