Laxman, what are you plans for enabling this and replacing the existing
non-dmaengine APB DMA driver? We will need to convert:

* The fuse WAR stuff in arch/arm/mach-tegra
* The ASoC driver in sound/soc/tegra

This will require some thought and dependency management between the
various subsystems.

Vinod,

It may be best to apply this series along in a topic branch that you
merge into the dmaengine branch, and I can pull into Tegra if/when I
need. Or, if you ack it, I can take it all through the Tegra tree if you
want. That wouldn't allow patch 1 to be use by others though.

Thanks.
