From 9c587c05d715ca8461342c2cb3b4a67036b5c22b Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 22 Aug 2011 08:45:15 +0100 Subject: ARM: 7045/1: mach-lpc32xx: break out GPIO driver specifics The file is included from upper directories and deal with generic GPIO and gpiolib stuff. Break out the platform and driver specific defines and functions into its own header file.
