I came from some earlier comments from Dmitry:

https://lore.kernel.org/all/250945d2-3940-9830-63e5-beec5f44010b@linaro.org/

Earlier comments from Dmitry were about having bus and drivers in same 
module. I think same comment applies with mailbox built into the 
gunyah.ko (message queue is the provider and rsr_mgr is the consumer).

Thanks,
