Since this is a framework consideration, don't you think it would be
better to standardise the phandle name?  This is common practice when
coding at a subsystem level.  Some in use examples include; "clocks",
"power-domains", "mboxes", "dmas", "phys", "resets", "gpios", etc.

Considering the aforementioned examples, I figured "rprocs" would be
suitable.
