AM5716: What is the Phytec Phycore AM5716 CPU Clock Frequency & what is the overclocking process for the AM5716?

1) What is the clock frequency for the AM5716?

2) How can I change the clock frequency in Linux for the AM5716?

3) What is the process to overclock the AM5716?  For Raspberry PI the process is to modify the Config.txt

See www.raspberrypi.org/.../overclocking.md

4) Why is there no frequency under sys on the AM5716, nor a scaling_cur_freq on the AM5716?

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

/sys/devices/system/cpu/cpufreq# ls 

cat /sys/devices/system/cpu/cpu0/cpu_capacity
