Maybe I just want to highlight it applies to the PHY with Mac 
connection, actually I was named Rockchip at the beginning, as Heiko 
said, PHY is a wide range, so add a modifier to restrict it.

Yes, we use other external phys, like realtek and etc...

If we have any other phy in our socs, it also could be expanded at 
rockchip_phy_tbl{} at rockchip.c

it has been licensed from somebody.
