Fair enough explanation for clk_round_rate(). I guess I should take it 
as "it's up to the specific clock implementation on what it wants to do".

But what about the problem of a clock consumer trying to find a suitable 
frequency amongst the ones provided by a particular clock?

What are your thoughts on adding the following two APIs to linux/clk.h?
clk_round_rate_down/floor()
clk_round_rate_up/ceil()

Thanks,
