Subject: [PATCH 7/8] ARM: dts: Exynos5800: fix CPU OPP
Fix CPU operating points for Exynos5800 (it uses different
voltages than Exynos5420 and supports additional frequencies).
However don't use 2000MHz & 1900MHz OPPs (for A15 cores) and
1400MHz OPP (for A7 cores) until there is a separate DTS for
ODROID-XU3 Lite board (which doesn't support these higher
OPPs).
Based on Hardkernel's kernel for ODROID-XU3 board.
