Thanks for the hint. In my configuration CONFIG_CPU_FREQ will not be used, so I should be fine. IMHO the definition of the OPPs should be moved to the board specific files as well in a separate patch. The ones defined in da850.c are not the only possible configurations, other boards may as well use different OPPs. Anyway, my patch does not break CONFIG_CPU_FREQ for the boards that have a 24 MHz oscillator.
