One other option would be that Dave merges your K3 tag which was sent to
ARM SoC to net-next. Its based on v5.6-rc1, has no other dependencies,
is already in linux-next, should be immutable and safe to merge. This
has the advantage that no rebase is necessary on net-next.

git://git.kernel.org/pub/scm/linux/kernel/git/kristo/linux
tags/ti-k3-soc-for-v5.7

+ ARM SoC maintainers for their information and any advise.

Thanks,
