Also you mention Exynos5420, while Chirantan's patch removing MCT > node from exynos5420.dtsi, would suggest that it worked for him fine.

The upstream kernel doesn't boot on those systems with or without the mct so I wasn't able to test there. Although looking at the upstream device tree now I see that there is no entry for the arch timer in exynos5420.dtsi. Maybe it should be added in?
