DT is considered ABI. Once released, you should not be making changes which are not backwards compatible. All the PHY and MDIO properties you are adding here are unused in the driver. They all look sensible, and you should be able to make it work. But when you do come to make that implementation, this definition is the base of what you have to work with. Andrew
