From 52e3134423c3af4431fedb34f77e31cfff91e0c3 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Mon, 3 Mar 2008 12:43:23 -0800 Subject: ARM: OMAP: Use gpiolib Update OMAP to use the new GPIO implementation framework. This is just a quick'n'dirty update ... more code could now be removed, ideally as part of cleaning up the entire OMAP GPIO infrastructure ...
