The OTP registers overlap with the previous node, control at d800100.
Not sure what's the best way to structure the devicetree in this case,
maybe something roughly like the following (untested, unverified):

	control at d800100 {
		compatible = "nintendo,hollywood-control", "simple-mfd";
		reg = <0x0d800100 0x300>;
		ranges;

		otp at d8001ec {
			compatible = "nintendo,hollywood-otp";
			reg = <0x0d8001ec 0x8>;
		};
	};
