DDR Overclocking on XU4

A new higher DDR frequency is now available on XU4 series.
So far, only Android supports the frequency set.
Also you can adjust DDR frequency and governor using a new ODROID Utility.

# cat /sys/class/devfreq/exynos5-devfreq-mif/available_governors
simple_exynos   performance

# cat /sys/class/devfreq/exynos5-devfreq-mif/available_frequencies
165000  206000  275000  413000  543000  633000  728000  825000  933000

ODROID Utility has been updated with the new release version.
You can change devfreq governor and frequency using it.

Here is a AnTuTu benchmark score.
We checked the following two cases.

• Case 1 : cpu governor - performance / devfreq governor - performance / devfreq clock - 825MHz
• Case 2 : cpu governor - performance / devfreq governor - performance / devfreq clock - 933MHz
