I believe SAMSUNG_DMADEV cannot work in multiplatform, but we also don't need it any more. The rest looks good.

Thanks for the review.

The patch description is wrong. After this patch single-platform Exynos support is no longer available and it adds at least one serious regression (cpufreq) which should be fixed before merging this patch. Moreover it seems that this patch (#2) should be merged with patch #3 to preserve bisectability. Please also note that exynos_defconfig is no longer useful after these changes and can be be removed.

I know that many other platforms still have their own configs [*] but I would strongly prefer to have a single config supporting Exynos SoCs (that would be a multiplatform one) to simplify testing and prevent situations when something works with one config but not the other. [*] I also hope that they get removed in the longer-term..
