Subject: [to be tested] [PATCH] at91: switch to CLKDEV_LOOKUP
Date: Wed, 2 Feb 2011 07:24:54 +0100 [thread overview]
Message-ID: <1296627894-1612-1-git-send-email-plagnioj@jcrosoft.com> (raw)
with this first commit we do not change the clock naming convention so
does not need to switcht the AVR32 yet
