Hi Jebaraj,

In datasheet we have only max frequency. I will recommend you to use 930MHz for ARM and 750MHz for DSP for lowest frequencies.

Other approach can be to modify these clock freq through the clock framework:

processors.wiki.ti.com/index.php

To see if the rate you are targeting is possible for the clock or not, use clk_round_rate() with the clock pointer(clkp) acquired through clk_get(), pass target rate in Hz.
