Yes, clearly we do have a corner case today due to the mix of hwmod / DTS resource management. - Legacy boot + hwmod resources is OK - DTS boot with DTS resources will be OK - DTS boot with hwmod resources is not OK since the resource name will not be populated in the case resources are not named :-( If you are OK, I'll take that patch along with Vaibhav one to handle properly the resources from DTS long with the DTS patches I'm queuing for 3.7.
