[Gta04-owner] cpu frequency scaling

[Rico Rommel]

Hi,

I noticed, that cpu frequency scaling doesn't work for 3.7 kernel.

dmesg gives:


...
[    0.124877] find_device_opp: Invalid parameters
[    0.124908] find_device_opp: Invalid parameters
[    0.124938] find_device_opp: Invalid parameters

...

[    2.971710] cpu cpu0: omap_cpu_init: cpu0: failed creating freq table[-19]

Is there something missing in kernel or kernelconfig?
