From 8f2a68a07c058fca1d413e54f71c2e7e78a74ed4 Mon Sep 17 00:00:00 2001 From: Martin Krause Date: Thu, 3 Apr 2008 14:29:01 +0200 Subject: TQM5200: fix default IDE reset level Before the first call of ide_reset(), the level of the IDE reset signal on the TQM5200 is low (reset asserted). This patch sets the default value to high (reset not asserted). Currently this patch fixes no real problem, but it is cleaner to assert the reset signal only on demand, and not permanently.
