Hi Andrew,

Thank you for catching it. I didn't notice the settings because the file
is copied from the exiting fuji.dts with minor changes.

The delay is currently introduced on MAC side (by manually setting SCU
registers), but I guess I can update phy-mode to "rgmii-id" so the delay
can be handled by the PHY?


Thanks,

Tao
