From ba16ec7cabb3f1aa7bbcb7b9982c4402a2e8ec02 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 23 Apr 2009 11:10:40 -0700 Subject: ARM: OMAP: Remove old dead gpio expander code This should be done with GPIO calls. Patches against the mainline tree welcome to add the necessary working functionality back.
