The entire point of the series is to define a way of identifying required opp-kBps values for L3/DDR at different cpu frequencies. The required-opps is chosen as the way of showcasing the dependencies. Hence the need to for a superset cpu opp-table consisting of all possible cpu freq values supported by the family of SoCs and enabling only the opps that are supported by the board from the values read back from firmware. > > -- > Regards, > Sudeep
