From 9ea14d8cbbf1c8fc941e8e8a12aa0a3edc5c336e Mon Sep 17 00:00:00 2001 From: Tarun Kanti DebBarma Date: Tue, 30 Aug 2011 15:05:44 +0530 Subject: gpio/omap: use level/edge detect reg offsets By adding level and edge detection register offsets and then initializing them correctly according to OMAP versions during device registrations we can now remove lot of revision checks in these functions.
