Maybe a little sort? But keep rest as it is. Also in example.

		iommus = <&isp0_mmu>;
		phys = <&mipi_dphy_rx0>;
		phy-names = "dphy";
		power-domains = <&power RK3399_PD_ISP0>;

Move reg above #address-cells. Change that in example as well.

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