Subject: [PATCH 2/4] dt-bindings: nintendo-otp: Document the Wii and Wii U OTP support
Date: Wed, 19 May 2021 11:45:44 +0200 [thread overview]
Message-ID: <20210519094546.3954-3-linkmauve@linkmauve.fr> (raw)
In-Reply-To: <20210519094546.3954-1-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.
