From 1635ca4aaf835794401da33079e50ce1d6bbb5d0 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Mon, 17 May 2010 14:53:48 +0900 Subject: ARM: S3C24XX: Remove macros mapping GPIO number to base As part of the cleanup, remove the old macros mapping GPIO numbers to the base of the register now we have gpiolib to manage the GPIO mappings for us.
