Subject: [RFC PATCH v2 8/8] net: ethernet: mtk_eth_soc: add paths and SerDes
modes for MT7988
MT7988 comes with a built-in 2.5G PHY as well as SerDes lanes to
connect external PHYs or transceivers in USXGMII, 10GBase-R, 5GBase-R,
2500Base-X, 1000Base-X and Cisco SGMII interface modes.
Implement support for configuring for the new paths to SerDes interfaces
and the internal 2.5G PHY.
Add USXGMII PCS driver for 10GBase-R, 5GBase-R and USXGMII mode, and
setup the new PHYA on MT7988 to access the also still existing old
LynxI PCS for 1000Base-X, 2500Base-X and Cisco SGMII PCS interface
modes.
