Hi,
I have a design for adding the sgmii support to the Ethernet mac.
The Ethernet mac is interfaced to the SGMII core and the mdio interface
from the mac is connected to the sgmii core for querying the link status
and autonegotaiation status.
The external phy is connected to the i2c bus and it is accessed through
i2c controller.
I have tested this design with out registering phy framework and configured
the external phy using the i2c lib and modified the Ethernet driver to include
code for accessing the sgmii core using the mdio interface.
Now i am looking for a solution to implement the following requirement using the
existing phy framework. But it looks the current phy framework is using only
the mdio bus.
Could some one suggest the better approach or solution for
implementing the below
requirement.
