From 80b7a2e2498bcffb1a79980dfbeb7a1275577b28 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 29 Dec 2016 14:36:51 +0100 Subject: ARM: dts: exynos: Add CPU OPPs for Exynos4412 Prime Add CPU operating points for Exynos4412 Prime (it supports additional 1704MHz & 1600MHz OPPs and 1500MHz OPP is just a regular non-turbo OPP on this SoC). Also update relevant cooling maps to account for new OPPs. ODROID-X2/U2/U3 boards use Exynos4412 Prime SoC version so update their board files accordingly. Based on Hardkernel's kernel for ODROID-X2/U2/U3 boards.
