From ab88c66deace78989aa71cb139284cf7fb227ba4 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Fri, 28 Feb 2014 20:17:05 -0300 Subject: [media] rc: add wakeup_protocols sysfs file MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a wakeup_protocols sysfs file which controls the new rc_dev::enabled_protocols[RC_FILTER_WAKEUP], which is the mask of protocols that are used for the wakeup filter. A new RC driver callback change_wakeup_protocol() is called to change the wakeup protocol mask.
