Subject: [U-Boot] [PATCH 06/10] mx5 clocks: Fix get_ipg_per_clk()
Date: Tue, 14 Aug 2012 20:07:31 +0200 (CEST) [thread overview]
Message-ID: <362780271.2408594.1344967651378.JavaMail.root@advansee.com> (raw)
In-Reply-To: <1102157688.2408541.1344967559029.JavaMail.root@advansee.com>
This fixes the "IPG PERCLK" frequency printed by the clocks command.
It also fixes i2c support.
