From d88746652b4d133284d1fdd05b5e999e8f44c998 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Wed, 10 Dec 2008 17:37:16 -0800 Subject: omap mmc: Add better MMC low-level init This will simplify the MMC low-level init, and make it more flexible to add support for a newer MMC controller in the following patches. The patch rearranges platform data and gets rid of slot vs controller confusion in the old data structures. Also fix device id numbering in the clock code. Some code snippets are based on an earlier patch by Russell King .

Merged into this patch patch are various improvments and board support by Grazvydas Ignotas and David Brownell. Also change wire4 to be wires, as some newer controllers support 8 data lines.
