I wanted to see for myself, but I didn't find it.

arch/mips/boot/dts/ralink/mt7621.dtsi:

	usb: usb at 1e1c0000 {
		compatible = "mediatek,mt8173-xhci", "mediatek,mtk-xhci";
		reg = <0x1e1c0000 0x1000
		       0x1e1d0700 0x0100>;
		reg-names = "mac", "ippc";

		#address-cells = <1>;
		#size-cells = <0>;

		clocks = <&sysc MT7621_CLK_XTAL>;
		clock-names = "sys_ck";

		interrupt-parent = <&gic>;
		interrupts = <GIC_SHARED 22 IRQ_TYPE_LEVEL_HIGH>;
	};

Shiji, did you also submit a device tree patch somewhere? Not that
you're required to, for this patch to be accepted. I'm just curious.
