Samsung devel-dma for v3.4

Hi Arnd, Olof,

This is for Samsung dma stuff for v3.4 and depends on following:
next/cleanup-use-static
next/cleanup-exynos-clock

Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git
next/devel-samsung-dma

And conflicts will be happened in clock part. Here is my preferred resolution. The mach-exynos/clock.c can be removed with following:

arch/arm/mach-exynos/exynos-clock4.c

Hi,

given my feedback on the cleanup-exynos-clock pull request, I'm holding off on this one waiting on you to do the resolution of the conflicts. :-)

Thanks,

-Olof

Yes, your suggestion can avoid bad conflicts.

Olof, let me rebase this on top of new cleanup-exynos-clock you suggested and will send a new pull request.

Thanks.

Thanks.

Best regards,
Kgene.
