From f014ee320e8779c1798998f75bfc3cef2b46286f Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Thu, 5 Nov 2009 22:59:47 -0800 Subject: ARM OMAP3: RX-51 board - add initialization of gpio keys Initialize some of the RX-51 input GPIO lines as gpio keys. Enable gpio keys as a module in rx51_defconfig.
