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 patch "dt-bindings: clock: mediatek: add MT7988 clock IDs" being merged before. https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=807227 Changes since RFC v1: - drop patch inhibiting SGMII AN in 2500Base-X mode - make pcs-mtk-lynxi a proper platform driver - ... hence allowing to remove all the wrappers from the usxgmii driver - attach PEXTP to MAC instead of to USXGMII PCS Daniel Golle (8): dt-bindings: phy: mediatek,xfi-pextp: add new bindings phy: add driver for MediaTek pextp 10GE SerDes PHY net: pcs: pcs-mtk-lynxi: add platform driver for MT7988 dt-bindings: net: pcs: add bindings for MediaTek USXGMII PCS net: pcs: add driver for MediaTek USXGMII PCS dt-bindings: net: mediatek: remove wrongly added clocks and SerDes dt-bindings: net: mediatek,net: fix and complete mt7988-eth binding net: ethernet: mtk_eth_soc: add paths and SerDes modes for MT7988 .../devicetree/bindings/net/mediatek,net.yaml | 180 ++++++-- .../bindings/net/pcs/mediatek,usxgmii.yaml | 60 +++ .../bindings/phy/mediatek,xfi-pextp.yaml | 80 ++++ MAINTAINERS | 3 + drivers/net/ethernet/mediatek/mtk_eth_path.c | 122 +++++- drivers/net/ethernet/mediatek/mtk_eth_soc.c | 284 ++++++++++-- drivers/net/ethernet/mediatek/mtk_eth_soc.h | 107 ++++- drivers/net/pcs/Kconfig | 11 + drivers/net/pcs/Makefile | 1 + drivers/net/pcs/pcs-mtk-lynxi.c | 170 ++++++- drivers/net/pcs/pcs-mtk-usxgmii.c | 413 ++++++++++++++++++ drivers/phy/mediatek/Kconfig | 11 + drivers/phy/mediatek/Makefile | 1 + drivers/phy/mediatek/phy-mtk-pextp.c | 365 ++++++++++++++++ include/linux/pcs/pcs-mtk-lynxi.h | 1 + include/linux/pcs/pcs-mtk-usxgmii.h | 26 ++ 16 files changed, 1746 insertions(+), 89 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/pcs/mediatek,usxgmii.yaml create mode 100644 Documentation/devicetree/bindings/phy/mediatek,xfi-pextp.yaml create mode 100644 drivers/net/pcs/pcs-mtk-usxgmii.c create mode 100644 drivers/phy/mediatek/phy-mtk-pextp.c create mode 100644 include/linux/pcs/pcs-mtk-usxgmii.h
