Stephen Warren - Sept. 17, 2012, 4:02 p.m.
The Tegra code-base has contained both a legacy DMA and a dmaengine
driver since v3.6-rcX. This series flips Tegra's defconfig to enable
dmaengine rather than the legacy driver, and removes the legacy driver
and all client code.

The branch is based on v3.6-rc6 in order to pick up a bug-fix to the
ASoC Tegra PCM driver that's required for audio to work correctly when
using dmaengine.
