A different dependency should be noted in *this* patch. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

The SRAM memory sits just next to the Ethernet and dedicated for this purpose, at least in theory.

Is this example really > different enough to justify a whole other example? Starting from MT7988 the PCS needs to be referenced as pcs-handle in the MAC node, so that is a bit different. If you don't think that justifies including the additional example I will drop that. > > > + > > + soc { > > + #address-cells = <2>; > > + #size-cells = <2>; > > + > > + ethernet@15100000 { > > + compatible = "mediatek,mt7988-eth"; > > + reg = <0 0x15100000 0 0x80000>, <0 0x15400000 0 0x380000>; > > + interrupts = <GIC_SPI 196 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 197 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 198 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 199 IRQ_TYPE_LEVEL_HIGH>; > > + > > + clocks = <ðsys CLK_ETHDMA_XGP1_EN>, > > + <ðsys CLK_ETHDMA_XGP2_EN>, > > + <ðsys CLK_ETHDMA_XGP3_EN>, > > + <ðsys CLK_ETHDMA_FE_EN>, > > + <ðsys CLK_ETHDMA_GP2_EN>, > > + <ðsys CLK_ETHDMA_GP1_EN>, > > + <ðsys CLK_ETHDMA_GP3_EN>, > > + <ðsys CLK_ETHDMA_ESW_EN>, > > + <ðsys CLK_ETHDMA_CRYPT0_EN>, > > + <ðwarp CLK_ETHWARP_WOCPU2_EN>, > > + <ðwarp CLK_ETHWARP_WOCPU1_EN>, > > + <ðwarp CLK_ETHWARP_WOCPU0_EN>, > > + <&topckgen CLK_TOP_ETH_GMII_SEL>, > > + <&topckgen CLK_TOP_ETH_REFCK_50M_SEL>, > > + <&topckgen CLK_TOP_ETH_SYS_200M_SEL>, > > + <&topckgen CLK_TOP_ETH_SYS_SEL>, > > + <&topckgen CLK_TOP_ETH_XGMII_SEL>, > > + <&topckgen CLK_TOP_ETH_MII_SEL>, > > + <&topckgen CLK_TOP_NETSYS_SEL>, > > + <&topckgen CLK_TOP_NETSYS_500M_SEL>, > > + <&topckgen CLK_TOP_NETSYS_PAO_2X_SEL>, > > + <&topckgen CLK_TOP_NETSYS_SYNC_250M_SEL>, > > + <&topckgen CLK_TOP_NETSYS_PPEFB_250M_SEL>, > > + <&topckgen CLK_TOP_NETSYS_WARP_SEL>; > > + > > + clock-names = "xgp1", "xgp2", "xgp3", "fe", "gp2", "gp1", > > + "gp3", "esw", "crypto", > > + "ethwarp_wocpu2", "ethwarp_wocpu1", > > + "ethwarp_wocpu0", "top_eth_gmii_sel", > > + "top_eth_refck_50m_sel", "top_eth_sys_200m_sel", > > + "top_eth_sys_sel", "top_eth_xgmii_sel", > > + "top_eth_mii_sel", "top_netsys_sel", > > + "top_netsys_500m_sel", "top_netsys_pao_2x_sel", > > + "top_netsys_sync_250m_sel", > > + "top_netsys_ppefb_250m_sel", > > + "top_netsys_warp_sel"; > > + assigned-clocks = <&topckgen CLK_TOP_NETSYS_2X_SEL>, > > + <&topckgen CLK_TOP_NETSYS_GSW_SEL>, > > + <&topckgen CLK_TOP_USXGMII_SBUS_0_SEL>, > > + <&topckgen CLK_TOP_USXGMII_SBUS_1_SEL>, > > + <&topckgen CLK_TOP_SGM_0_SEL>, > > + <&topckgen CLK_TOP_SGM_1_SEL>; > > + assigned-clock-parents = <&apmixedsys CLK_APMIXED_NET2PLL>, > > + <&topckgen CLK_TOP_NET1PLL_D4>, > > + <&topckgen CLK_TOP_NET1PLL_D8_D4>, > > + <&topckgen CLK_TOP_NET1PLL_D8_D4>, > > + <&apmixedsys CLK_APMIXED_SGMPLL>, > > + <&apmixedsys CLK_APMIXED_SGMPLL>; > > + mediatek,ethsys = <ðsys>; > > + mediatek,infracfg = <&topmisc>; > > + #address-cells = <1>; > > + #size-cells = <0>; > > + > > + mac@0 { > > + compatible = "mediatek,eth-mac"; > > + reg = <0>; > > + phy-mode = "internal"; /* CPU port of built-in 1GE switch */ > > + > > + fixed-link { > > + speed = <10000>; > > + full-duplex; > > + pause; > > + }; > > + }; > > + > > + mac@1 { > > + compatible = "mediatek,eth-mac"; > > + reg = <1>; > > + phy-handle = <&int_2p5g_phy>; > > + }; > > + > > + mac@2 { > > + compatible = "mediatek,eth-mac"; > > + reg = <2>; > > + pcs-handle = <&usxgmiisys0>; > > + phy-handle = <&phy0>; > > + }; > > + > > + mdio_bus: mdio-bus { > > + #address-cells = <1>; > > + #size-cells = <0>; > > + > > + /* external PHY */ > > + phy0: ethernet-phy@0 { > > + reg = <0>; > > + compatible = "ethernet-phy-ieee802.3-c45"; > > + }; > > + > > + /* internal 2.5G PHY */ > > + int_2p5g_phy: ethernet-phy@15 { > > + reg = <15>; > > + compatible = "ethernet-phy-ieee802.3-c45"; > > + phy-mode = "internal"; > > + }; > > + }; > > + }; > > + }; > > -- > > 2.43.0
