Looks almost good to me!

I just recalled that there is also a 64bit variant of Tegra124, the Tegra132. Hence
the Tegra30+ Kconfig entry should look like this (it's also worthy to break the lines
for readability):

diff --git a/drivers/devfreq/Kconfig b/drivers/devfreq/Kconfig
index ccb1a68c4b51..bd2efbc27725 100644
--- a/drivers/devfreq/Kconfig

        help
          This adds the DEVFREQ driver for the Tegra family of SoCs.

Could you please adjust the patches like I'm suggesting? I'll approve yours change
then and won't re-spin the first batch of the patches.
