Subject: [PATCH] ARM: S3C24XX: Fix configuration of gpio port sizes on S3C24XX.
Date: Wed, 11 Sep 2013 09:46:13 +0100 [thread overview]
Message-ID: <1378889173-7437-1-git-send-email-jose.goncalves@inov.pt> (raw)
Some GPIO line limits are incorrectly set which, for instance,
does not allow nRTS1 (GPH11) configuration on a S3C2416 chip.
Signed-off-by: José Miguel Gonçalves <jose.goncalves@inov.pt>
