Subject: [PATCH] ARM: dts: fix incorrect vdd_arm voltage range for Exynos4412 based boards
Date: Sat, 18 Jan 2014 16:41:23 +0530 [thread overview]
Message-ID: <1390043483-1219-1-git-send-email-thomas.ab@samsung.com> (raw)
From: Thomas Abraham <thomas.ab@samsung.com>
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.
