Sorry - I picked the @linux.intel.com address from git blame. Hmm.. is
the mark.gross@intelc.om in MAINTAINERS still valid?

Thanks - I appreciate the feedback!

Thanks - I appreciate the feedback :-)

As I said earlier, I think the maximum frequency can act as a level of
energy efficiency request. If a workload knows that a certain level of
performance is adequate, the maximum frequency request can prevent
e.g. ondemand unnecessarily raising the frequency.
