+From 842f7d2c4d392c0571cf72e3eaca26742bebbd1e Mon Sep 17 00:00:00 2001
+From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
+Date: Tue, 2 Dec 2014 17:48:02 +0100
+Subject: ARM: mvebu: use the cpufreq-dt platform_data for independent clocks
+
+This commit adjusts the registration of the cpufreq-dt driver in the
+mvebu platform to indicate to the cpufreq driver that the platform has
+independent clocks for each CPU.
