clk_round_rate() returns the clock rate which will be set if you ask

with that same argument.
So essentially, clk_set_rate() should be:
static int clk_set_rate(struct clk *clk, unsigned long rate)
{
rate = clk_round_rate(clk, rate);
return set_actual_rate(clk, rate);
}
From what I understand, you're saying clk_round_rate() is defined as
what clk_set_rate() would do, which is call clk_round_rate() and then
set the rate with whatever is returned by clk_round_rate()? Isn't that a
recursive definition?
I'll play along though. The use of the function is to determine what the
rate will be if I call clk_set_rate(), but what is the implementation of
it suppose to be. I guess now I'm asking what should clk_set_rate() do?
Round up, down, to the closest value, or just fail if it's not exact.
