From 4c6c32b3f856346158161a8c9824b4dd2bff0893 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Mon, 29 Nov 2010 08:58:14 +0100 Subject: ARM: mx25: fix offset for usb host controller MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In commit 2c20b9f (ARM: mx25: dynamically allocate mxc-ehci devices) I changed the offset to the value specified in the reference manual intending to test this change on hardware. This slipped through and now prooved to be wrong. So fix it and add a comment about the documentation being wrong.
