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.
