From 9aaf4d2a08182b7ef6d939642a6d92564bd83b2f Mon Sep 17 00:00:00 2001 From: Emmanuel Gil Peyrot Date: Tue, 10 Aug 2021 16:30:35 +0100 Subject: [PATCH] dt-bindings: nintendo-otp: Document the Wii and Wii U OTP support MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
