This series aims to add support for GMAC2 and GMAC3 of the MediaTek MT7988 SoC. 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.
