Regarding this patch I'm trying to determine whether it makes sense to have ops or
sync_ops set to null. Your[v3 01/14]  patch commit explains that ops can be null in case of
synchronisation.
But it seems deprecated with the sync_ops introduction...

And if sync_ops is null, is it still necessary to define a remoteproc device?

Regards
Arnad
