While the vendor SDK stuffs all this into their Ethernet driver, I've tried to seperate things into a PHY driver, a PCS driver as well as changes to the existing Ethernet and LynxI PCS driver. +--------------+ +----------------+ +------------------+ | +---| USXGMII PCS |---+ | | Ethernet MAC | +----------------+ | PEXTP SerDes PHY | | +---| SGMII PCS |---+ | +--------------+ +----------------+ +------------------+ Alltogether this allows using GMAC2 and GMAC3 with all possible interface modes, including in-band-status if needed. Note that this series depends on series "dt-bindings: clock: mediatek: add MT7988 clock IDs"[1] as well as "dt-bindings: watchdog: mediatek,mtk-wdt: add MT7988 watchdog and toprgu"[2] being merged before.
