From 20a761a32bc3e52a02d3b7909ab988cfdd1077f8 Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Sun, 16 Feb 2014 02:08:40 +0900 Subject: [PATCH] ARM: dts: update vdd_arm voltage range for exynos4412 based boards To allow EXYNOS4412 based Odroidx and Origen-quad boards to operate between 200MHz to 1.4Ghz, update the vdd_arm voltage range to operate between these cpu clock speeds.
