Understood, but from a git perspective the commit ids have changed.
While git can deal with trivial re-commits like this, my understanding
is that should be avoided for upstream merges. Otherwise, I could just
cherry-pick them and re-commit them in my tree.

Ultimately, the people working off of those branches do need them to be
stable to merge their branches. So are you saying your l2x0 branch
(91c2ebb90b1890abc648ba9dec5608cbc97e1cb9) is now stable? Can you
publish it as a branch. iMX6Q is also dependent on it.
