I had no confidence for some changes in the patch series, since James
is more easier to reach out hardware persons, so James kindly took over
and refined the patches (Thanks a lot!).

I hope Al could take a look for the patches, and myself also will give
a review and test for this series.

P.s. @James, I think some patches have been refactored, so it's good
to add "Co-developed-by:" tag or changing the author name for you.
Will comment on this when I review patches.

Thanks,
Leo
