How to enable dvfs in omap.

[Mohamed Thalib H <mohamed@e-consystems.com>]

Hi all,

I am using omap 2.6.37 running overo board. I have enabled the following 
option in the kernel menunconfig,


CPU Power Management --->
│ │ [*] CPU Frequency scaling
│ │ [ ] Enable CPUfreq debugging
│ │ <*> CPU frequency translation statistics
│ │ [*] CPU frequency translation statistics details
│ │ Default CPUFreq governor (ondemand) --->
│ │ -*- 'performance' governor
│ │ <M> 'powersave' governor
│ │ <*> 'userspace' governor for userspace frequency scaling
│ │ -*- 'ondemand' cpufreq policy governor
│ │ <*> 'conservative' cpufreq governor
│ │ [ ] CPU idle PM support


but still I could find the sys and entry in 
/sys/devices/system/cpu/cpufreq/ directory. Could some one help me to 
enable DVFS.

root@overo:/sys/devices/system/cpu# ls
cpu0 kernel_max online possible
cpufreq offline perf_events present
root@overo:/sys/devices/system/cpu# cd cpu0/
root@overo:/sys/devices/system/cpu/cpu0# ls
crash_notes
root@overo:/sys/devices/system/cpu/cpu0# cd ..
root@overo:/sys/devices/system/cpu# cd cpufreq/
root@overo:/sys/devices/system/cpu/cpufreq# ls
root@overo:/sys/devices/system/cpu/cpufreq#
