Yes, that's the one. That series is fairly self-contained, but Dmitry's
power management set has dependencies that pull in the regulator, clock
and ARM SoC trees.

I did a test merge of the driver unification series with a branch that
has Dmitry's patches and all the dependencies and there are no conflicts
so that, fortunately, doesn't further complicates things.

Do you want me to send you a pull request with Dmitry's memory
controller changes? You could then apply the unification series on top,
which should allow this SMMU series to apply cleanly on top of that.

I can also carry all these changes in the Tegra tree and send a PR in a
few days once this has seen a bit more testing in linux-next, which also
makes sure it's got a bit more testing in our internal test farm.
