Merge tag 'tegra-for-3.7-dmaengine' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/cleanup
ARM: tegra: switch to dmaengine
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.
* tag 'tegra-for-3.7-dmaengine' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
ASoC: tegra: remove support of legacy DMA driver based access
spi: tegra: remove support of legacy DMA driver based access
ARM: tegra: apbio: remove support of legacy DMA driver based access
ARM: tegra: dma: remove legacy APB DMA driver
ARM: tegra: config: enable dmaengine based APB DMA driver
+ sync to 3.6-rc6
