The numbers are actually real, but the example simply lost their context
because I copied the node from the S7 dtsi (not yet submitted), where
the controller sits under the APB bus node (bus@fe000000) and the bus
ranges make the addresses relative to it.

		apb: bus@fe000000 {
			compatible = "simple-bus";
			reg = <0x0 0xfe000000 0x0 0x480000>;
			#address-cells = <2>;
			#size-cells = <2>;
			ranges = <0x0 0x0 0x0 0xfe000000 0x0 0x480000>;

			clkc_periphs: clock-controller@0 {
				compatible = "amlogic,s7-peripherals-clkc";
				reg = <0x0 0x0 0x0 0x49c>;
				#clock-cells = <1>;
				...

In V2 I'll use an absolute address for the sake of clarity (PLL has the
same issue).

Thanks,
