From e4243f13d10e5fbe2b84e211dcac3bc6e0792167 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Mon, 21 Feb 2011 18:35:28 +0800 Subject: mmc: mxs-mmc: add mmc host driver for i.MX23/28 This adds the mmc host driver for Freescale MXS-based SoC i.MX23/28. The driver calls into mxs-dma via generic dmaengine api for both pio and data transfer. Thanks Chris Ball for the indentation patch.
