I have no comments on the actual code changes, only that the patch would benefit from a more complete message. Please explain a bit when the issue happens (only when the fsl-mc bus probe is not defered - meaning no smmu). Also mention in the commit message as well that you are moving the dprc and allocator drivers registration at the subsys_initcall_sync stage while the misc_init() is called at subsys_initcall. Ioana
