[PATCH v2 4/7] ARM: dts: Exynos: add cpu nodes, opp and cpu clock frequency table

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Thomas Abraham <thomas.ab@xxxxxxxxxxx>

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.
