Subject: ARM: S3C24XX: Fix configuration of gpio port sizes on S3C24XX.
X-Git-Tag: v4.14-rc1~8239^2~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=035b2f7c8e64f2c7f87e1e11373b17c5dd1fbff4;p=platform%2Fkernel%2Flinux-rpi.git

ARM: S3C24XX: Fix configuration of gpio port sizes on S3C24XX.

Some GPIO line limits are incorrectly set which, for instance,
does not allow nRTS1 (GPH11) configuration on a S3C2416 chip.
