[4.4.y-cip 05/15] PM / OPP: Rename OPP nodes as opp@<opp-hz>


Chen-Yu Tsai (Moxa) <wens@...>
 

From: Viresh Kumar <viresh.kumar@linaro.org>

commit 754dcf35f34698661801ae1d391efa02affe83a7 upstream.

It would be better to name OPP nodes as opp@<opp-hz> as that will ensure
that multiple DT nodes don't contain the same frequency. Of course we
expect the writer to name the node with its opp-hz frequency and not any
other frequency.

And that will let the compile error out if multiple nodes are using the
same opp-hz frequency.
