Subject: [PATCH 4/7] i.MX53: enable pull up on I2C0 pins
Date: Tue, 21 Feb 2012 01:27:36 +0100	[thread overview]
Message-ID: <1329784059-6006-4-git-send-email-eric@eukrea.com> (raw)
In-Reply-To: <1329784059-6006-1-git-send-email-eric@eukrea.com>

this allows I2C to work on boards which don't have external pull up
(like LOCO board)
