From 897359d596ca406aaa9f9687b439b4498b579d7f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Fri, 5 Feb 2010 17:40:28 +0100 Subject: [PATCH] arm/mx2: define seperate gpio port descriptions for imx21 and imx27 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As the gpio ports have different addresses on imx21 and imx27 there are two different port descriptions needed if not relying on the overloaded cpp macro IO_ADDRESS. So some cpp magic is added to minimize code duplication.
