exynos5420 and its reference board, smdk5420.

Oh, sorry about that, if so, it should be fixed before -rc1. Just note that I
thought since exynos5800 is very similar with exynos5420 so I didn't ask
Chander to test the series on exynos5800 based board...Just asked to test with
Nico's mcpm series. BTW, unfortunately I have no exynos5800-peach-pi...

Yes I think so. As you can see in exynos5800.dtsi, it is including exynos5420.

Hmm...why is the problem happened at last? Not at that time? :(
I need to figure it out...
Thanks,
