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
