From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nishanth Menon Subject: [PATCH] ARM: dts: omap3-ldp: fix mmc configuration Date: Mon, 20 Jan 2014 17:34:33 -0600 Message-ID: <1390260873-22354-1-git-send-email-nm@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-omap-owner@vger.kernel.org To: =?UTF-8?q?Beno=C3=AEt=20Cousson?= , Balaji T K , Tony Lindgren Cc: devicetree@vger.kernel.org, linux-omap@vger.kernel.org, linux-arm-kernel@lists.infradead.org, Nishanth Menon List-Id: devicetree@vger.kernel.org MMC1 is the only MMC interface available on the platform. Further, since the platform is based on older revision of SoC which is not capable of doing multi-block writes, mark it so and add pinmux to ensure that all relevant pins are configured for non-MMC boot mode.
