target_cpu_speed. And then finally setting the highest requested freq in the

I urge you to read the ARM ARM, and specifically the section dedicated
to trapping access to CP15 operations. If you do, you'll quickly notice
that you *cannot* trap accesses to the timer subsystem.
I read it again. The ARMv7 manual said Is accessible from
Most of the drivers do following in their -target_index() routines:
struct cpufreq_freqs freqs;
freqs.old = old freq...
freqs.new = new freq...
cpufreq_notify_transition(policy, freqs, CPUFREQ_PRECHANGE);
/* Change rate here */
