From 5e1ac7db04f963e230ffa0a39c5df376733f8c0b Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Tue, 29 May 2012 14:40:04 +0800 Subject: [PATCH] ARM: ux500: Enable Device Tree support mmci for Snowball Allow proper initialisation for MMC via the mmci driver for the Snowball low-cost development board using DT. At the moment we continue to use DMA setup from platform code. Once the DMA generic DT bindings have been completed we can then port the remainder over to DT.
