Guenter Roeck df3f5efe10 hw/net/imx_fec: Support two Ethernet interfaces connected to single MDIO bus ... The SOC on i.MX6UL and i.MX7 has 2 Ethernet interfaces. The PHY on each may be connected to separate MDIO busses, or both may be connected on the same MDIO bus using different PHY addresses. Commit 461c51ad42 ("Add a phy-num property to the i.MX FEC emulator") added support for specifying PHY addresses, but it did not provide support for linking the second PHY on a given MDIO bus to the other Ethernet interface. To be able to support two PHY instances on a single MDIO bus, two properties are needed: First, there needs to be a flag indicating if the MDIO bus on a given Ethernet interface is connected. If not, attempts to read from this bus must always return 0xffff. Implement this property as phy-connected. Second, if the MDIO bus on an interface is active, it needs a link to the consumer interface to be able to provide PHY access for it. Implement this property as phy-consumer.
