This is not a show stopper for accepting the patch, just wondering if you are somehow trying to get that switch controlled by the rtl8366 DSA driver as well?

It's on this > branch: > https://github.com/arinc9/openwrt/commits/realtek-work-asus_rt-ac88u Your dsa,member proper looks reversed, you would want it to be: dsa,member = <1 0>; to indicate that these are indeed disjoint DSA trees with the tree being 1 and the switch being member 0 (the one and only). This part of the driver/binding looks a bit weird too: switch@1 { + compatible = "realtek,rtl8365mb"; + /* 22 = MDIO (has input reads), 21 = MDC (clock, output only) */ + mdc-gpios = <&chipcommon 6 GPIO_ACTIVE_HIGH>; + mdio-gpios = <&chipcommon 7 GPIO_ACTIVE_HIGH>; + reset-gpios = <&chipcommon 14 GPIO_ACTIVE_LOW>; this is clearly a MDIO-attached switch, so it should be a children of the GPIO controller node. There is a hardware MDIO controller on the BCM5301X so you should be able to avoid using bit-banging here and instead using the BCM5301X's MDIO controller proper. > > It doesn't work as is, likely missing further configuration, which I'm > clueless to figure out myself.

That works for me, which is why I already applied your patch.

I took linksys panamera device tree as an example, this device is very similar to Asus RT-AC88U. https://github.com/Broadcom/stblinux/blob/devicetree/next/arch/arm/boot/dts/bcm47094-linksys-panamera.dts I commented out the "reg" property on switch@1 so we can see if it finds the switch while scanning PHY addresses on mdio 200. I don't know if the default "interrupt-controller" and "compatible = "realtek,smi-mdio", "dsa-mdio";" specification is correct, so I took them out for now. mdio-mux@18003000 { /* BIT(9) = 1 => external mdio */ mdio@200 { reg = <0x200>; #address-cells = <1>; #size-cells = <0>; switch@1 { compatible = "realtek,rtl8365mb"; #address-cells = <1>; #size-cells = <0>; reset-gpios = <&chipcommon 10 GPIO_ACTIVE_LOW>; reset-names = "robo_reset"; /* reg = <0>;*/ dsa,member = <1 0>; pinctrl-names = "default"; pinctrl-0 = <&pinmux_mdio>; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; label = "lan8"; }; port@1 { reg = <1>; label = "lan7"; }; port@2 { reg = <2>; label = "lan6"; }; port@3 { reg = <3>; label = "lan5"; }; port@4 { reg = <4>; label = "cpu"; ethernet = <&sw0_p5>; phy-mode = "rgmii"; fixed-link { speed = <1000>; full-duplex; }; }; }; }; }; }; Here's relevant part of the bootlog.

You still need to provide the Ethernet switch's address on the MDIO bus which appears to be 0. Auto-probing of devices only works for Ethernet PHYs, not for "pure" MDIO devices such as Ethernet switches.

After fixing "dsa,member" on the original specification, the log slightly changed. I'm going to see if I can switch to the net-next kernel on OpenWrt to test the driver further.
