From db63a493838473e3ae87e0db06bb6ddd817f20a2 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Sun, 6 Mar 2011 00:40:19 +0800 Subject: [PATCH] ARM: mxs: add helper macro for pad control This patch is to add pad control helper macro to make the code easy to read. The need is being seen when adding pad definitions for LCDIF which gets ~30 pads to define.
