Weijie Gao	b4b266fc13	net: phy: Add MediaTek built-in 2.5Gb ethernet PHY driver ... The MediaTek MT7987/MT7988 SoCs features a built-in 2.5Gb PHY connected to GMAC1. The PHY supports 10/100/1000/2500 Mbps full-duplex only. The PHY requires one or two firmware files. Firmware for MT7988 has already been added to upstream: mediatek/mt7988/i2p5ge-phy-pmb.bin. MT7987 has two firmware files which will be add to upstream later: i2p5ge-phy-pmb.bin and i2p5ge-phy-DSPBitTb.bin. Environment variable can be set for firmware data loading: mt7987_i2p5ge_load_pmb_firmware for i2p5ge-phy-pmb.bin mt7987_i2p5ge_load_dspbit_firmware for i2p5ge-phy-DSPBitTb.bin mt7988_i2p5ge_load_pmb_firmware for i2p5ge-phy-pmb.bin This driver allows dedicated weak functions to be overridden by board to provide the firmware data: mt7987_i2p5ge_get_fw() for MT7987 mt7988_i2p5ge_get_fw() for MT7988 To enable the PHY, add the following not to device tree: &eth1 { status = "okay"; phy-mode = "xgmii"; phy-handle = <&phy15>; phy15: ethernet-phy@15 { compatible = "ethernet-phy-ieee802.3-c45"; reg = <15>; phy-mode = "xgmii"; }; }; Signed-off-by: Sky Huang <SkyLake.Huang@mediatek.com> Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>	2025-09-18 15:43:05 -06:00
