[PATCH v2 0/2] Add Qualcomm MSM ADM DMAEngine driver

From: Ravi Kumar V
Date: Fri Jan 06 2012 - 07:47:49 EST


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
