Subject: [PATCH v2 3/3] nvmem: meson-efuse: add write support
Date: Mon, 23 Apr 2018 14:41:49 +0200 [thread overview]
Message-ID: <20180423124149.3077-4-jbrunet@baylibre.com> (raw)
In-Reply-To: <20180423124149.3077-1-jbrunet@baylibre.com>
Add write support to the meson-gx efuse driver.
Beware, this efuse is one time programmable !
