Normally frequency scaling is manged by scaling governors. By default the active scaling governor in r10.2 BSP is "userspace".
I changed the scaling governor to "performance" so that processor operates at max possible freq ie. 1GHz. But still current freq is 400Mhz. I checked the active scaling governor it is "performance".
How can we set the processor operating freq to get max performance?
As you want the Android to run at max., have you try to disable the DVFS?
Or you can try to modify the dvfs by refering this https://community.freescale.com/message/314988#314988
