Since all Exynos platforms have been converted to dmaengine and many of the older platforms are in the process of conversion they do not need to use the legacy s3c-dma APIs for DMA but can instead use the standard ASoC dmaengine helpers. This both allows them to benefit from improvements implemented in the generic code and supports multiplatform. This patch includes some fixes from Padma for Exynos SoCs, her testing was on a slightly earlier version of the patch due to unrelated breakage preventing testing.
