From b0d5217cfb0a2357ac076977400c648cccff6154 Mon Sep 17 00:00:00 2001 From: Kyungmin Park Date: Tue, 17 Nov 2009 08:41:16 +0100 Subject: ARM: S5PC1xx: add gpiolib and external/gpio interrupt support Add support for gpiolib calls. This is based on the gpiolib implementation from plat-s3c64xx tree. Add support for external interrupts for GPIO H banks. Add support for GPIO interrupts for all banks.
