From 7ced5eab39809539e8fc7f3fb561bd3001d535e7 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Mon, 3 May 2010 17:19:49 +0900 Subject: ARM: S3C24XX: Add extended GPIO used on S3C2443 and beyond Add the GPIO banks that are used on the S3C2443 and above to the list of available GPIOS. Currently we do not have any limit on the SoC GPIO, so these are being registered whether the SoC has them or not. It is currently up to the user not to try and use them.
