Subject: [PATCH 2/3] video: mxsfb: Remove custom method for retrieving GPIO

From: [email-masked] (Fabio Estevam)
Date: Wed, 3 Apr 2013 19:01:13 -0300

From: Fabio Estevam <[email-masked]>

mxs device tree files should use the standard gpio reset binding, so no need to
have this code inside the driver anymore.
