Hello The DP83822 Ethernet PHY has the ability to connect via a Fiber port. The DP83825 or DP83826 do not have this ability. In order to keep the same driver the DP83822 and the 825/826 phy_driver call backs need to be changed so that the DP83822 has it's own call back for config_init and adds a probe call back. A devicetree binding was added to set the signal polarity for the fiber connection. This property is only applicable in fiber mode and is optional in fiber mode.
