From 96974a249b0cf3537f49115a59be67e2c54f315c Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Mon, 25 Apr 2011 01:09:05 +0300 Subject: omap: consolidate touch screen initialization among different boards Add common-board-devices.c that will contain the code for peripheral devices initializatoin shared between multiple boards. Start small with touchscreen initialization.
