Also prepare support for MT7988 which has been done while net-next was closed. Note that this series depends on commit 697c3892d825 ("regmap: apply reg_base and reg_downshift for single register ops") to not break mt7530 pcs register access. For SGMII and 1000Base-X mode to work well it also depends on commit 193250ace270 ("net: ethernet: mtk_eth_soc: fix RX data corruption issue") which has already been merged via the net tree. The whole series has been tested on MT7622+MT7531 (BPi-R64), MT7623+MT7530 (BPi-R2), MT7981+GPY211 (GL.iNet GL-MT3000) and MT7986+MT7531 (BPi-R3). On the BananaPi R3 a variete of SFP modules have been tested, all of them (some SGMII with PHY, others 2500Base-X or 1000Base-X without PHY) are working well now. Changes since v11: * remove patch "net: ethernet: mtk_eth_soc: fix RX data corruption issue" as it has already been merged via net tree * add commits fixing 1000Base-X and 2500Base-X modes after phylink_pcs conversion * completely remove mtk_sgmii.c as only about 20 lines were left in that file * Add commits from Lorenzo for MT7988 as requested by him Changes since v10: * improve mediatek,mt7981-eth dt-bindings * use regmap_set_bits instead of regmap_update_bits where possible * completely remove mtk_sgmii.c * no need to keep struct mtk_sgmii either as it had only a single element Changes since v9: * fix path in mediatek,sgmiisys dt-binding Changes since v8: * move mediatek,sgmiisys dt-bindings to correct net/pcs folder * rebase on top of net-next/main so series applies cleanly again Changes since v7: * move mediatek,sgmiisys.yaml to more appropriate folder * don't include twice in PCS driver, sort includes Changes since v6: * label MAC MCR bit 12 in 08/12, MediaTek replied explaining its function Changes since v5: * drop dev pointer also from struct mtk_sgmii, pass it as function parameter instead * address comments left for dt-bindings * minor improvements to commit messages Changes since v4: * remove unused dev pointer in struct pcs_mtk_lynxi * squash link timer check into correct follow-up patch Changes since v3: * remove unused #define's * use BMCR_* instead of #define'ing our own constants * return before changing registers in case of invalid link timer Changes since v2: * improve dt-bindings, convert sgmisys bindings to dt-schema yaml * fix typo Changes since v1: * apply reverse xmas tree everywhere * improve commit descriptions * add dt binding documentation * various small changes addressing all comments received for v1 Daniel Golle (13): net: ethernet: mtk_eth_soc: add support for MT7981 SoC dt-bindings: net: mediatek,net: add mt7981-eth binding dt-bindings: arm: mediatek: sgmiisys: Convert to DT schema dt-bindings: arm: mediatek: sgmiisys: add MT7981 SoC net: ethernet: mtk_eth_soc: set MDIO bus clock frequency net: ethernet: mtk_eth_soc: reset PCS state net: ethernet: mtk_eth_soc: only write values if needed net: ethernet: mtk_eth_soc: fix 1000Base-X and 2500Base-X modes net: ethernet: mediatek: Fix SerDes link status if not in SGMII mode net: ethernet: mtk_eth_soc: ppe: add support for flow accounting net: pcs: add driver for MediaTek SGMII PCS net: ethernet: mtk_eth_soc: switch to external PCS driver net: dsa: mt7530: use external PCS driver Lorenzo Bianconi (6): net: ethernet: mtk_eth_soc: add MTK_NETSYS_V1 capability bit net: ethernet: mtk_eth_soc: move MAX_DEVS in mtk_soc_data net: ethernet: mtk_eth_soc: rely on num_devs and remove MTK_MAC_COUNT net: ethernet: mtk_eth_soc: add MTK_NETSYS_V3 capability bit net: ethernet: mtk_eth_soc: convert caps in mtk_soc_data struct to u64 net: ethernet: mtk_eth_soc: add support for MT7988 SoC .../arm/mediatek/mediatek,sgmiisys.txt | 27 -- .../devicetree/bindings/net/mediatek,net.yaml | 53 ++- .../bindings/net/pcs/mediatek,sgmiisys.yaml | 55 +++ MAINTAINERS | 7 + drivers/net/dsa/Kconfig | 1 + drivers/net/dsa/mt7530.c | 277 +++-------- drivers/net/dsa/mt7530.h | 47 +- drivers/net/ethernet/mediatek/Kconfig | 2 + drivers/net/ethernet/mediatek/Makefile | 2 +- drivers/net/ethernet/mediatek/mtk_eth_path.c | 36 +- drivers/net/ethernet/mediatek/mtk_eth_soc.c | 448 +++++++++++++++--- drivers/net/ethernet/mediatek/mtk_eth_soc.h | 301 ++++++++---- drivers/net/ethernet/mediatek/mtk_ppe.c | 114 ++++- drivers/net/ethernet/mediatek/mtk_ppe.h | 25 +- .../net/ethernet/mediatek/mtk_ppe_debugfs.c | 9 +- .../net/ethernet/mediatek/mtk_ppe_offload.c | 8 + drivers/net/ethernet/mediatek/mtk_ppe_regs.h | 14 + drivers/net/ethernet/mediatek/mtk_sgmii.c | 203 -------- drivers/net/pcs/Kconfig | 7 + drivers/net/pcs/Makefile | 1 + drivers/net/pcs/pcs-mtk-lynxi.c | 308 ++++++++++++ include/linux/pcs/pcs-mtk-lynxi.h | 13 + 22 files changed, 1266 insertions(+), 692 deletions(-) delete mode 100644 Documentation/devicetree/bindings/arm/mediatek/mediatek,sgmiisys.txt create mode 100644 Documentation/devicetree/bindings/net/pcs/mediatek,sgmiisys.yaml delete mode 100644 drivers/net/ethernet/mediatek/mtk_sgmii.c create mode 100644 drivers/net/pcs/pcs-mtk-lynxi.c create mode 100644 include/linux/pcs/pcs-mtk-lynxi.h base-commit: 36e5e391a25af28dc1f4586f95d577b38ff4ed72
