Please notice that the word is *inter* dependent, not *in* dependent.

There is a build dependency for the patches. The first two "soc/tegra"
must be applied first.

The "soc/tegra: pmc: Enable core domain support for Tegra20 and Tegra30"
*must* be the last applied patch if we want to preserve bisectability.
The core voltage scaling can be enabled only once all the drivers got
the power management support.

The rest could be applied out-of-order.
