Paul, In linux-omap clock framework, most clocks have no set_rate in their definition in clock34xx.h, but defined DEFAULT_RATE in clksel_rate structures, this Will only allow some pre-set rates for some clocks and Can not get a more flexible rates if driver wants to Change the clock rate usng clk_set_rate. What is the benefit of this implementation? We want to understand this before we made the change In case we missed some imprtant background of This implementation.
