Subject: [PATCH] ARM: r7s72100: fix bus clock calculation
Date: Fri, 28 Feb 2014 09:32:55 +0000 [thread overview]
Message-ID: <1393579975-19619-1-git-send-email-wsa@the-dreams.de> (raw)
From: Wolfram Sang <wsa@sang-engineering.com>
The picture in the datasheet is a little misleading, yet the divider of
the bus_clk is 1/3 and not 2/3.
