Don't add "->" to your replies, it doesn't make it more readable but less.

Why? So, as far as I got it your dividers are nothing but 0,1,2...
i.e.
Freqs: 400  500  600  700  800
div:      4      3      2      1      0

right? That's what you are doing in exynos5440. So just add this in your
probe after doing: dev_pm_opp_init_cpufreq_table

for(i = 0; all-available-freqs; i++)
    dvfs_info->freq_table[i].driver_data = dvfs_info->freq_count - i;

And this will work with changes in dts files.
