Hi Doug,  Brain,
    Thanks for the reply.
    Sorry I forgot these patches have been sent earlier, and Frank
have some explained and discussed with Heiko.
Please see https://patchwork.kernel.org/patch/9255245/
    Perhaps we can move to that patch tree to continue the discussion.

    I think Frank and William will help us to continue checking these.

I only briefly read that discussion, but AFAICT it doesn't actually
address all the comments/quetions we had here. For instance, the
power_off() vs. delayed-work race in your USB2 PHY driver (is that
intentional?). Also, the question of why PHY (auto?)suspend is relevant.

I'll check again tomorrow.
