Sorry, I don't have much to base my judgement upon. I did search for the
"VPHY" string and found it to be accessed in the dev_ops->r_phy() and
dev_ops->w_phy() implementations, suggesting that it is more than just
that? These methods are used for accessing the registers of the embedded
PHYs for user ports. I don't see what is the connection with RGMII on
the CPU port.
