From mboxrd@z Thu Jan 1 00:00:00 1970 From: wens@csie.org (Chen-Yu Tsai) Date: Wed, 3 Dec 2014 14:36:03 +0800 Subject: [PATCH 08/10] ARM: dts: sun9i: Enable mmc0 on A80 Optimus Board In-Reply-To: <1417588565-26215-1-git-send-email-wens@csie.org> References: <1417588565-26215-1-git-send-email-wens@csie.org> Message-ID: <1417588565-26215-9-git-send-email-wens@csie.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Enable the micro-sd slot on the A80 Optimus Board, which is connected to mmc0. This adds the card-detect gpio and enables mmc0. This patch also adds a 3V fixed regulator, which is the default I/O voltage level.
