It doesn't matter what 'rate' is when this function is called. The callback is supposed to determine what the clk rate will be if a consumer called clk_set_rate() with 'rate'. Don't fail that if the rate is requested to be larger than max, just tell clk_round_rate() that if you ask for something larger you'll get PLL_MAX_FREQ. > + return -EINVAL; > + } > +

The clock tree of K1 SoC contains three main types of clock hardware (PLL/DDN/MIX) and is managed by several independent controllers in different SoC parts (APBC, APBS and etc.), thus different compatible strings are added to distinguish them. Some controllers may share IO region with reset controller and other low speed peripherals like watchdog, so all register operations are done through regmap to avoid competition.
