Hi Rob,

so the way you prefer is this one (use new file for additions and includin=
g the board dts):

arch/arm64/boot/dts/mediatek/mt7622-bpi-r64-mt7531.dts (example for mt7531=
-phy)

/*

/dts-v1/;

#include "mt7622-bananapi-bpi-r64.dts"

/ {
        gsw: gsw@0 {
                compatible =3D "mediatek,mt753x";
                mediatek,ethsys =3D <&ethsys>;
                #address-cells =3D <1>;
                #size-cells =3D <0>;
        };
};

&gsw {
        mediatek,mdio =3D <&mdio>;
        mediatek,portmap =3D "wllll";
        mediatek,mdio_master_pinmux =3D <0>;
        reset-gpios =3D <&pio 54 0>;
        interrupt-parent =3D <&pio>;
        interrupts =3D <53 IRQ_TYPE_LEVEL_HIGH>;
        status =3D "okay";

        port5: port@5 {
                compatible =3D "mediatek,mt753x-port";
                reg =3D <5>;
                phy-mode =3D "rgmii";
                fixed-link {
                        speed =3D <1000>;
                        full-duplex;
                };
        };

        port6: port@6 {
                compatible =3D "mediatek,mt753x-port";
                reg =3D <6>;
                phy-mode =3D "2500base-x";
                fixed-link {
                        speed =3D <2500>;
                        full-duplex;
                };
        };
};

at least it compiles and after decompile the new nodes are visible...

is there any way to drop nodes (in case dsa-driver gets merged i don't nee=
d it in the other 2)? i can disable them, but they will be present.

regards Frank
