Subject: [PATCH 3/7] at91: Fix uhpck clock rate in upll case
Date: Fri, 16 Sep 2011 14:23:44 +0200 [thread overview]
Message-ID: <1316175828-19748-3-git-send-email-plagnioj@jcrosoft.com> (raw)
In-Reply-To: <1316175828-19748-1-git-send-email-plagnioj@jcrosoft.com>

commit 8251544f9e28058e54c4f35b7cd13b0d191d7555
Author: Ryan Mallon <ryan@bluewatersys.com>
The uhpck clock should be divided from the utmi clock, not its parent
(main). This change is mostly cosmetic as the uhpck rate value is not
used anywhere except for the debugfs clock output.
