[PATCH 2/4] dt-bindings: nintendo-otp: Document the Wii and Wii U OTP support

From: Emmanuel Gil Peyrot
Date: Wed May 19 2021 - 05:05:43 EST


Both of these consoles use the exact same two registers, even at the
same address, but the Wii U has eight banks of 128 bytes memory while
the Wii only has one, hence the two compatible strings.
