Hi,
This small series is needed to use DVFS on Armada 37xx. When DVFS is enabled the CPU clock setting is done using an other set of registers from the North Bridge Power Management block.
The series adds the possibility to modify the CPU frequency using the associate load level matching the target frequency. However configuring the frequencies for each load is done by the cpufreq driver submitted in a separate series.
Obviously having both series (cpufreq and clk) is needed to support DVFS on Armada 37xx, but there is no dependencies between the series (for building or at runtime).
Thanks,
Gregory
