OK good to hear it's not the change to ti-sysc. That should be all pretty
much standard Linux driver related changes.

Argh not again, the fw_devlink changes seem to be causing all kind of
issues. Any ideas what the issue here might be? It might be worth testing
with v6.0-rc7 too as it has a series of fixes to related issues.
