So historically there's often a lot of dependencies, either build-time
or runtime, between Tegra clock patches and other work. That's why we
ended up with this model where I collect Tegra clock patches in the
Tegra tree and it's not uncommon to end up with the clock branch being
a dependency of one of the other branches.

I did send this to Mike and Stephen about 1 1/2 weeks ago, but it does
not look like they've pulled it into the clk tree yet.

I typically highlight the dependencies in the pull request, but looks
like I forgot to do that this time around.

Given the above, might be best to hold off on this for a bit until the
clock branch was pulled by Mike or Stephen.
