Yup, that's expected. It avoids any backwards compatibility issues.
The watchdog patchset has been pulled by Jason Cooper in two branches;
if my memory doesn't fail me, they are: mvebu/watchdog and mvebu/dt.
However, the mvebu/dt branch seemed to conflict with Andrew's multi-v5
work, so I haven't advised you to merge it as well. And since the watchdog
can work with the old DT, it's not a big issue.
Just remember to update your DTB.

Thanks! The watchdog work is already merged, but maybe Jason Cooper can take
care of adding your tested-by.
