The DT patch (patch4), is available on an immutable branch "genpd_dt" too. From now on, I will continue to put changes for genpd DT bindings on the above branch, to allow SoC maintainers to pull it in to manage potential dependent updates to DTS files. Kind regards Uffe

The v6.7/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers for inclusion in their intermediate git branches in order to be sent to Linus during the next merge window, or sooner if it's a set of fixes. In the cases of fixes, those will be merged in the current release candidate kernel and as soon they appear on the Linux master branch they will be backported to the previous Stable and Long-Stable kernels [2]. The intermediate git branches are merged daily in the linux-next tree [3], people are encouraged testing these pre-release kernels and report issues on the relevant mailing-lists. If problems are discovered on those changes, please submit a signed-off-by revert patch followed by a corrective changeset.

By works I mean, vim4 is able to boot without panics but drops to emergency shell as expected. I was not able to find patches 1-3 and 5 at amlogic/for-next. Is there a reason why amlogic/for-next only have DTs changes? Tested-by: Lucas Tanure <tanure@linux.com>

From now I'll only take the DT and the genpd/ changes will go into the new subsystem maintained by Ulf. You should use the daily linux-next tree which would contain both trees merged.
