I would group this:

		serial1: serial@d00 {
			compatible = "ns16550a";
			reg = <0xd00 0x100>;

			reg-io-width = <4>;
			reg-shift = <2>;

			clocks = <&sysc MT7621_CLK_UART2>;

			interrupt-parent = <&gic>;
			interrupts = <GIC_SHARED 27 IRQ_TYPE_LEVEL_HIGH>;

			no-loopback-test;

			pinctrl-names = "default";
			pinctrl-0 = <&uart2_pins>;

			status = "disabled";
		};

Same goes for patch 2.
