From 0164cbf4390fbcd7125fc8d476a451a3efa14c5d Mon Sep 17 00:00:00 2001 From: Byungho Min <bhminjames@gmail.com> Date: Tue, 23 Jun 2009 21:40:22 +0900 Subject: ARM: S5PC100: GPIO and I2C S5PC100 has more GPIO group then previous one. It has 34 groups of GPIO, while S3C6410 has 17 groups. For now, only header files are written.
