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.
