Subject: [PATCH 0/2] ARM: add Exynos4412 Prime SoC support

Hi,

This patchset adds support for Exynos4412 Prime SoC (it supports
additional 1704MHz & 1600MHz CPU OPPs and 1500MHz CPU OPP is just
a regular non-turbo OPP on this SoC).

ODROID-X2/U2/U3 boards use Exynos4412 Prime SoC version so their
board files are updated accordingly.

This patchset brings 21% CPU performance increase on affected
boards (as tested on ODROID-U3 board).

Best regards,
