So Rajendra's usage of > "operating-points-v2-qcom-level" [1] doesn't have a frequency but > Jordan's do. So I guess it makes sense that Jordan's have the > fallback compatible but Rajendra's don't? Is having it useful to s/w that doesn't understand "operating-points-v2-qcom-level"? If so, then add "operating-points-v2". If not, then don't. I don't really care either way. Just don't do both ways and document which way is correct.
