These SoC integrate a Gigabit Ethernet MAC with RGMII/RMII/MII interface, with a similar design than previous SoCs such MT8188 or MT8195. This series is based on net-next tree (sha1: 7b6ab4dbc156). It has been tested on Mediatek Genio 520-EVK (MT8371) and 720-EVK (MT8391) boards, which both integrate an Airoha AN8801R Ethernet PHY, with hardware enablement series ([1]). It has been also tested on Mediatek Genio 510-EVK (MT8370, variant of MT8188) and 1200-EVK (MT8395, variant of MT8195).

Lunn) - Dropped in patch 3 mediatek,tx/rx-delay-ps description changes in bindings and patch description (A. Lunn) - Patch 4: - Used single delay stage divider define for both RX and TX case to simplify implementation - Added MII delay definitions - Dropped Reviewed-By trailer due to changes - Patch 5: - Fixed MII/RGMII delay stage divider inversion (Sashiko) - Used single delay stage divider define for both RX and TX case to simplify implementation - Added patch 6 to add the standard internal delay properties use - Patch 7: - Renamed delay stage divider fields in variant struct (M. Chevallier) - Simplified patch implementation by using one delay stage divider per mode in variant structure and commonizing delay computation in new single private function - Dropped "net: stmac: mediatek: use TX clock phase shift in RGMII mode with 1Gbps speed" previously present in v2 and v3, as suggested by A. Lunn - Rebased patches 8 to 10 over previous patches modifications - Link to v3: https://lore.kernel.org/r/20261016-dwmac-mediatek-mt8189-v3-0-25daf2bbcf35@collabora.com Changes in v3: - Rebased on net-next (sha1: 6b3e73774815) - Added Reviewed-By trailers in patch 3 and 5 - Added patch 1 to fix unit in rx/tx delay property description (Sashiko) - Patch 2: - Reworded patch description to add clock list details - Removed the specific MT8189 clocks list so the axi and apb clocks are also described for this compatible too and reworked the clock list and number check - Added mediatek,rmii-clk-from-mac as not allowed for MT8189 (Sashiko) - Added patch 4 to simplify TX/RX delay handling in mt2712_set_delay, as suggested by M. Chevallier and modified following patches accordingly - Fixed in patch 7 tx_rgmii_delay_stage_div null case and register value in mt8195_fix_mac_speed (Sashiko) - Added in patch 9 the axi and apb clocks to MT8189 clock lists - Link to v2: https://lore.kernel.org/r/20260924-dwmac-mediatek-mt8189-v2-0-430bd74d5ef9@collabora.com Changes in v2: - Rebased on net-next (sha1: 528de6832b21) - Dropped "net: stmmac: mediatek: rename MT2712 and MT8195 variant methods" and "net: stmmac: mediatek: add support for TX deallocation adjustment feature" patches, present in v1 (M. Chevallier) - Patch 1: - Removed rmii_internal clock from required clock list (A. Lunn) - Added MT8189 stage delay divider values in "mediatek,rx-delay-ps" and "mediatek,rx-delay-ps" property description (Sashiko) - Updated commit description - Added patch 2 to simplify TX/RX delay handling in mt8195_set_delay - Added patch 3 to add RX/TX delay stage divider in platform data - Patch 4: - Replace MT8195_PERI_ETH_CTRL_BASE by MT8195_PERI_ETH_CTRL_OFFSET to harmonize the variable and definition naming (A. Lunn) - Added Reviewed-By tag - Added patch 5 to add the TX Clock phase shift use in RGMII and in 1G speed - Patch 6: - Reworded flag and define names to explicit a bit more what the feature does - Updated commit description - Patch 7: - Added the new definitions and needed fields in platform data - Updated commit description to add the info about MT8189 RX/TX delay stage divider and maximum values, and remove reference about stage fine feature - Link to v1: https://lore.kernel.org/r/20260707-dwmac-mediatek-mt8189-v1-0-17f345eaaca3@collabora.com --- Louis-Alexis Eyraud (10): dt-bindings: net: mediatek-dwmac: fix unit in rx/tx delay property description dt-bindings: net: mediatek-dwmac: deprecate rx/tx delay vendor properties dt-bindings: net: mediatek-dwmac: add support for MT8189 SoC net: stmmac: mediatek: simplify TX/RX delay handling in mt8195_set_delay net: stmmac: mediatek: simplify TX/RX delay handling in mt2712_set_delay net: stmmac: mediatek: use standard internal delay properties net: stmmac: mediatek: add RX/TX delay stage divider in platform data net: stmmac: mediatek: add PERI_ETH_CTRLx register offset in platform data net: stmmac: mediatek: add support for TX clock output enable feature net: stmmac: mediatek: add support for MT8189 SoC .../devicetree/bindings/net/mediatek-dwmac.yaml | 52 ++- .../net/ethernet/stmicro/stmmac/dwmac-mediatek.c | 374 +++++++++++++-------- 2 files changed, 278 insertions(+), 148 deletions(-) --- base-commit: 7b6ab4dbc156e2f96419715130b3d5738a306c93 change-id: 20260703-dwmac-mediatek-mt8189-9dafe3984951 Best regards, -- Louis-Alexis Eyraud
