Linux/DRA725: Set MPU clock lower than 1000MHz

Part Number:DRA725

Tool/software: Linux

Hi TIs:

Due to some reasons, we need to do an experiment which set the frequency of MPU to run at 800 MHz

According to the spec, the OPP_NOM of DRA725 is 1000 MHz

Is it possible to set MPU frequency lower than 1000 MHz?

And how do i set voltage of MPU in this situation?

thanks

Kenny
