| |
When switching from 10GBase-R/5GBase-R/USXGMII to one of the interface modes provided by mtk-pcs-lynxi we need to make sure to always perform a full configuration of the PHYA.
Implement pcs_disable op which resets the stored interface mode to PHY_INTERFACE_MODE_NA to trigger a full reconfiguration once the LynxI PCS driver had previously been deselected in favor of another PCS driver such as the to-be-added driver for the USXGMII PCS found in MT7988.
