This adds the DEVFREQ driver for Exynos4210 memory bus (vdd_int)
and Exynos4212/4412 memory interface and bus (vdd_mif + vdd_int).
It reads PPMU counters of memory controllers and adjusts
the operating frequencies and voltages with OPP support.
- To operate with optimal voltages, ASV support is required
- (CONFIG_EXYNOS_ASV).
+ This does not yet operate with optimal voltages.
