From 2099c301274b8273e9cf68fc76dd03225681b5df Mon Sep 17 00:00:00 2001

Subject: [PATCH 4/7] i.MX53: enable pull up on I2C0 pins
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
this allows I2C to work on boards which don't have external pull up
(like LOCO board)
