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.
