Hi Rob, I get Laurent/Rob comments before, and explained why we needs
these DT properties, so far, I didn't get any response.

Hi Rob Herring and Laurent, for the DT property lane0/1-swing, Google
engineer has strong demond for them, they don't want to move DP swing
adjusting to kernel, thus may cause change the driver code in each
project, so config them in DT is a best option.

Thanks,
Xin
