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.
