From 9a34bc61160167319fcfa59842cc0373487d533b Mon Sep 17 00:00:00 2001 From: Mike Turquette Date: Wed, 29 Sep 2010 23:38:01 -0700 Subject: Input: omap4-keypad - wake-up on events & long presses Program keyboard controller to generate a wake-up request on events and on long key presses. It will not generate wake-up requests on timeouts since driver code does not handle them. This allows keyboard to wake-up OMAP from suspend.
