Subject: [PATCH 1/2] dt-bindings: nintendo-otp: Document the Wii and Wii U OTP support
Date: Tue, 10 Aug 2021 16:30:35 +0100 [thread overview]
Message-ID: <20210810153036.1494-2-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20210810153036.1494-1-srinivas.kandagatla@linaro.org>
From: Emmanuel Gil Peyrot <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.
