From mboxrd@z Thu Jan 1 00:00:00 1970 From: prakash.pm@ti.com (Manjunathappa, Prakash) Date: Thu, 28 Mar 2013 18:42:01 +0530 Subject: [PATCH v7 4/5] ARM: davinci: da850: add mmc DT entries In-Reply-To: <1364476322-15882-3-git-send-email-prakash.pm@ti.com> References: <1364476322-15882-3-git-send-email-prakash.pm@ti.com> Message-ID: <1364476322-15882-5-git-send-email-prakash.pm@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add DT entry for MMC. Also add entry for pinmux information. Tested: 1) Without GPIO card detection and EDMA support as DT support for GPIO and EDMA are yet come. 2) By creating/deleting files and mounting/unmounting the partition.
