clk_round_rate will call round_rate_index();
--------------------------
static int
round_rate_index(struct clk *clk, unsigned long drate, unsigned long *rate)
{
unsigned long tmp = 0, prev_rate = 0;
int index;
if (!clk->calc_rate)
return -EFAULT;
------------------------------------------
The cpu_clk don't have calc_rate, clk_round_rate always return fault.
Stanley.
