Okay, so I've separated the first two patches out into a separate stable branch that I can share between the Tegra and drm/tegra trees to pull in the build dependency and then I've applied the driver patches to those two trees and I've verified that the two branches build correctly. I've not done any runtime testing, but I'll trust you on that. > 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. One last remaining question: I don't think I can apply that one patch if it requires that all the others are enabled first because it would basically create a circular dependency. Can I pick up the final 7 patches (the DT ones) independently of that one patch without things breaking? If so, one option we could try is to wait for both Tegra and drm/tegra trees to get merged into v5.17-rc1 and then send that one patch (which is only a 4-line diff) right after v5.17-rc1 so that it makes it into v5.17-rc2. That avoids the circular dependency and should get everything enabled for v5.17. Do you see any problems with that? Thierry
