The arm64 is for the DT maintainer. Please send it separately after this
series is applied (if it gets applied)

This was a comment on your v2. Did you fix the orphan/ordering issue ?
If you did, you probably should mention it here.
If you did not, I'm probably not going to review this further until you do.
