Subject: [PATCH 2/2] ARM: dts: igep0020: Add SD card write-protect pin.
Date: Fri, 6 May 2016 23:02:34 +0200 [thread overview]
Message-ID: <1462568554-7868-2-git-send-email-enric.balletbo@collabora.com> (raw)
In-Reply-To: <1462568554-7868-1-git-send-email-enric.balletbo@collabora.com>
A host device that supports write protection should refuse to write to
an SD card that is designated read-only when write-protect is set. This
is an optional feature of the SD specification.
