RGMU a.k.a Reduced Graphics Management Unit is a small state machine with the sole purpose of providing IFPC support. Compared to GMU, it doesn't manage GPU clock, voltage scaling, bw voting or any other functionalities. All it does is detect an idle GPU and toggle the GDSC switch. So it doesn't require iommu & opp table.
