Subject: [PATCH v4 4/5] dt-bindings: at25: add reference for the wp-gpios property
Date: Tue, 7 Jan 2020 10:29:21 +0100 [thread overview]
Message-ID: <20200107092922.18408-5-ktouil@baylibre.com> (raw)
In-Reply-To: <20200107092922.18408-1-ktouil@baylibre.com>
As the at25 uses the NVMEM subsystem, and the property is now being
handled, adding reference for it in the device tree binding document,
which allows to specify the GPIO line to which the write-protect pin
is connected.
