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
