Re: [PATCH v2 4/7] ARM: dts: Exynos: add cpu nodes, opp and cpu clock frequency table
Hi Thomas,
From: Thomas Abraham thomas...@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.
