Hi Andrew,

I've already reached out to Ryan and Jacky from ASPEED regarding the
topic a few weeks ago. Originally I thought MAC-side clock delay was
only needed for fixed-linked (for example, in darwin dts), but looks
like it's also impacting platforms with PHY..

Anyways I will follow up with Jacky/Ryan after addressing all the
comments for this patch series.


Thanks,

Tao
