Sometimes it is possible and reasonable to adjust the parent clock rate to improve precision of the child clock, e.g., if the child clock has no siblings. clk_round_parent() is a new addition to the SH clock-framework API, that implements such an optimization for child clocks with divisors, taking all integer values in a range.
