[PATCH v6 6/7] ARM: dts: Exynos5800: fix CPU OPP

Bartlomiej Zolnierkiewicz
2015-12-15T17:37:00Z

Fix CPU operating points for Exynos5800 (it use different
voltages than Exynos5420 and supports additional frequencies).
However don't use 2000MHz & 1900MHz OPPs (for A15 cores) and
1400MHz OPP (for A7 cores) for now as they are not available
on all boards.

Based on Hardkernel's kernel for ODROID-XU3 board.

Changes by Ben Gamari:
- Port to operating-points-v2
