Subject: [PATCH] ARM64: dts: meson-gx: make efuse read-only
Date: Fri, 16 Mar 2018 15:50:21 +0100 [thread overview]
Message-ID: <20180316145021.8517-1-jbrunet@baylibre.com> (raw)
efuse is one time programmable, so it is safer to deny write request
to this memory, unless the user is savvy enough to remove the read-only
flag from DTB
