OPP == OPerating Point == P-state
In System-on-chip Land OPP is a very common term, roughly defined as a frequency & voltage pair that makes up a performance state.
In other words, OPP is the P-state of the non-ACPI world.
Similarly DVFS is sometimes confused as a brand new file system, but it is also a very standardized acronym amongst SoC vendors meaning frequency and voltage scaling.
