[PATCHv2,3/4] ARM: mvebu: use the cpufreq-dt platform_data for independent clocks

Commit Message

Thomas Petazzoni Sept. 10, 2014, 12:08 p.m. UTC

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.
