1.1 Change Cortex-A53 Clock Frequency

Maximum frequency of A53 cores on AM62Ax varies based on speed grade of the device and the VDD_CORE voltage applied. AM62A SK-LP EVM Rev E2 supports 0.75 V VDD_CORE mode operation which supports operation of maximum core frequency of 1.25 GHz. To obtain peak performance of the device, the setup was modified to run the A53 cores on AM62Ax at 1.4 GHz.
