From b63fd6ce71226e5e048e2035ba202b53f89a1825 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20R=C3=A9tornaz?= Date: Tue, 24 Jan 2012 14:22:01 +0100 Subject: [PATCH] i.MX SDMA: Fix burstsize settings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 6584cb88 (ARM i.MX dma: Fix burstsize settings) fixed the mxcmmc driver but forgot to fix the SDMA driver to handle the correct burtsize. This make the SD card access works again with DMA on i.MX31 boards.
