No, there isn't, but in Documentation/networking/dsa/dsa.rst we do have
a list of dsa_switch_ops functions which used to be comprehensive
(but now needs to be updated again due to development that happened in
the meantime). I suppose that if you do a thorough job of documenting
the synchronization rules, you could add that information to this file.
This would be similar to how we have the "struct net_device synchronization
rules" section in Documentation/networking/netdevices.rst.
