[PATCH v2 4/7] ARM: dts: Exynos: add cpu nodes, opp and cpu clock frequency table
Thomas Abraham
ta.omasab at gmail.com
Sat Jan 18 07:10:54 EST 2014
From: Thomas Abraham <thomas.ab at samsung.com>
For all Exynos based platforms, add CPU nodes, operating points and cpu
clock frequency table for migrating from Exynos specific cpufreq driver
to using generic cpufreq-cpu0 driver.
