Regarding OMAP3630 Zoom3 Board Clock Speed

Hi,
How can read DPLL1 (MPU_CLK) speed related registers in ported TI linux kernel.
i am facing in figuting out the values.
After going through TRM and given formula (SYS_CLK*2*M)/(N+1)*M2 value is coming as 1200 Mhz having a SYS_CLK of 26 Mhz.

but while reading through cat /proc/cpuinfo it is giving 600Mhz. and this is not same and it is giving some wrong oitput as ARM7 core as a processor name althjough it is a ARM11 coretex 8 processor.

Did my registers reading code is wrong as 1200Mhz is not possible.

Is there any proper way to read the corresponding CPRM MPU registers.

Please help us as we are in critical stage.

Thanks and regards
Abhay Kumar
