In general, according to phy.rst, RGMII delay should be done by phy, but
some MoCA product need RGMII delay in MAC. These two requirements
conflict. Is there any suggestion to solve the conflict?

Implementing the delay in the PHY is just a recommendation, not a
requirement. However, as i said, you need to be careful what is pass
to phylib. If the MAC is implementing "rgmii-id", whatever makes it
way down to phy_attach_direct() needs to be "rgmii". If the MAC
implements "rgmii-rxid", the phy should be implementing "rgmii-txid",
etc. If this is wrong, you get both the MAC and the PHY implementing
delays, and bad things happen.
