I saw those posts. The CPSW ip version changes tracks the internal IP
changes and there is no possible way to track the offset changes. For
example CPTS sub module offsets in DM814x and AM335x are different
though the CPTS version is same in both IP versions. So keeping these
offset in DT will make the same driver works directly with DT changes
for future SoC.

I saw those posts. The CPSW ip version changes tracks the internal IP

example CPTS sub module offsets in DM814x and AM335x are different
