Since I don't think anyone has mentioned this point on the public lists,
I'll echo the earlier internal discussion on this patch. I think the PMC
driver should handle this all entirely internally. The PMC HW module
doesn't have well-defined sub-modules, and hence we shouldn't represent
sub-modules in DT. DT should represent HW structure, not Linux SW structure.
