Ok, given that I haven't ever reviewed this code, I had a few questions
that I couldn't easily figure out by looking at your code:
	- what is the lifecycle of your 'struct device' usage?  Who
	  creates it, who frees it, and who accesses it?
	- do you have any Documentation/ABI entries?
	- root_dprc_count, why are you using an atomic variable for
	  this?  What is it for other than "look, I'm running!"?
	- don't call pr_info() in fsl_mc_bus_driver_init(), no need to
	  say anything if all goes well.  Same goes with random
	  dev_info() calls, please remove.

That's good enough for now, I think the answer to the first question is
going to cause more to come out :)
