parentcpsw: support both silicon versions (diff)
cpts: introduce time stamping code and a PTP hardware clock.
This patch adds a driver for the CPTS that offers time stamping and a PTP hardware clock. Because some of the CPTS hardware variants (like the am335x) do not support frequency adjustment, we have implemented this in software by changing the multiplication factor of the timecounter.
