The OTP registers overlap with the previous node, control@d800100.
Not sure what's the best way to structure the devicetree in this case,
maybe something roughly like the following (untested, unverified):
control@d800100 {
compatible = "nintendo,hollywood-control", "simple-mfd";
reg = <0x0d800100 0x300>;
ranges;
otp@d8001ec {
compatible = "nintendo,hollywood-otp";
reg = <0x0d8001ec 0x8>;
};
};
