Date: Fri, 6 May 2016 23:02:34 +0200 From: Enric Balletbo i Serra <enric.balletbo@...labora.com> To: linux-kernel@...r.kernel.org, devicetree@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-omap@...r.kernel.org Cc: Javier Martinez Canillas <javier@...hile0.org>, Tony Lindgren <tony@...mide.com> Subject: [PATCH 2/2] ARM: dts: igep0020: Add SD card write-protect pin. 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.
