Hi Alexey,
We got review comments to merge dt changes in one patch, we are still discussing on
how to organize next version, I think we can add the Co-developed-by tag if remoteproc
is sent as a single patch in next version, "Written with" description will be used
to avoid SOB chain too long.
Thanks,
Jingyi
