From 4869710caedf5f7cc6a893846e4045d0f35ac737 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 15 Dec 2015 18:33:20 +0100 Subject: [PATCH] ARM: dts: Extend existing CPU OPP for exynos5800 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.
