From 12bd257532708a4d5be4b8548ff121a45ff88f5d Mon Sep 17 00:00:00 2001 From: Ville Syrjala Date: Mon, 9 Jun 2008 22:06:45 +0300 Subject: [PATCH] at91_mci: Fix byte mode transitions. The byte mode support fails to clear the byte mode bit in the command register, possibly leaving byte mode enabled with the counters programmed in non-byte mode.
