Will this interface provides information of max number if OPPs supported and
the frequency corresponding to eah OPP level?
Notification of OPP level change to DSP
------------------------------------------
MPU Bridge is required to inform the DSP about OPP level change for load
predictor use in DSP;
this is done as part of in post notification in dspbridge. Do we have
support for Post Notification in this framework?
Please let us know your comments.
Thanks & regards
