This patch removes the following from "config ARM_TEGRA_CPUFREQ":

	default y
	help
	  This adds the CPUFreq driver support for TEGRA SOCs.

I think that option should be left unchanged, such that this patch
*just* adds the new option without changing the existing one. If you do
that, then you can completely drop patch 4/4.

Other than that, this series looks fine.
