Subject: [PATCH v4 2/5] dt-bindings: nintendo-otp: Document the Wii and Wii U OTP support
Date: Sun, 1 Aug 2021 09:38:19 +0200 [thread overview]
Message-ID: <20210801073822.12452-3-linkmauve@linkmauve.fr> (raw)
In-Reply-To: <20210801073822.12452-1-linkmauve@linkmauve.fr>
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.
