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.
