See, "ARM: EXYNOS: Support DMA for Exynos5250 SoC"
http://lists.infradead.org/pipermail/linux-arm-kernel/2012-February/085434.html

But this merge window is not including it :(

OK.

Well...there is a MDMA1 on EXYNOS5250 SoC, so if we can use MDMA1,
should be MDMA1 for dma-pl330.3 but...I think, I need to check :)

Thanks.
