[PATCH] ARM: dts: Add missing CPU frequencies for Exynos5422/5800
From: Bartlomiej Zolnierkiewicz
Date: Tue Dec 13 2016 - 11:55:44 EST
Add missing 2000MHz & 1900MHz OPPs (for A15 cores) and 1400MHz OPP
(for A7 cores). Also update common Odroid-XU3 Lite/XU3/XU4 thermal
cooling maps to account for new OPPs.
Since new OPPs are not available on all Exynos5422/5800 boards modify
dts files for Odroid-XU3 Lite (limited to 1.8 GHz / 1.3 GHz) & Peach
Pi (limited to 2.0 GHz / 1.3 GHz) accordingly.
Tested on Odroid-XU3 and XU3 Lite.
