Is there a portable/generic approach for other drivers that may want to use arm-cpufreq.c? arm_clk is not normally defined for my SoC and I don't see an easy way to pull it in.
Could you tell me the details? Is your board arch/arm/mach-highbank/ Rob maintained? clk API is the most generic way for arm as far as I find out.
Thanks Richard

cpufreq needs cpu clock to change frequency.
