From 90c62bf08f5823faa097271f3346a9142769b9ac Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Wed, 10 Dec 2008 17:37:17 -0800 Subject: omap mmc: Add low-level initialization for hsmmc controller Add low-level initialization for hsmmc controller. 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.
