From mboxrd@z Thu Jan 1 00:00:00 1970 From: merker@debian.org (Karsten Merker) Date: Thu, 10 Dec 2015 21:32:00 +0100 Subject: [PATCH 2/3] ARM: dts: sun7i: Olimex A20-SOM-EVB: Enable mmc3 (baseboard SD socket) In-Reply-To: <1449779521-754-1-git-send-email-merker@debian.org> References: <1449779521-754-1-git-send-email-merker@debian.org> Message-ID: <1449779521-754-3-git-send-email-merker@debian.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The Olimex A20-SOM-EVB is an evaluation board for the Olimex A20-SOM system-on-module. The baseboard provides a full-size SD socket (connected to mmc3) in addition to the micro-SD socket on the SOM itself (which is connected to mmc0). Enable the mmc3 controller in the dts.
