Thanks!

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 at 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 at 18003000 {

		/* BIT(9) = 1 => external mdio */
		mdio at 200 {
			reg = <0x200>;
			#address-cells = <1>;
			#size-cells = <0>;

			switch at 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 at 0 {
						reg = <0>;
						label = "lan8";
					};

					port at 1 {
						reg = <1>;
						label = "lan7";
					};

					port at 2 {
						reg = <2>;
						label = "lan6";
					};

					port at 3 {
						reg = <3>;
						label = "lan5";
					};

					port at 4 {
						reg = <4>;
						label = "cpu";
						ethernet = <&sw0_p5>;
						phy-mode = "rgmii";

						fixed-link {
							speed = <1000>;
							full-duplex;
						};
					};
				};
			};
		};
	};

Here's relevant part of the bootlog. Full bootlog is in the attachments.

Looks like the switch is not on 0x200, what else can we try?
