Add the rt linux 4.1.3-rt3 as base
Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> We lose all the git history this way and it's not good. We should apply another opnfv project repo in future. Change-Id: I87543d81c9df70d99c5001fbdf646b202c19f423 Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

+Description:
+ This file is provided by the iio-trig-sysfs stand-alone trigger
+ driver. Writing this file with any value triggers an event
+ driven driver, associated with this trigger, to capture data
+ into an in kernel buffer. This approach can be valuable during
+ automated testing or in situations, where other trigger methods
+ are not applicable. For example no RTC or spare GPIOs.
+ X is the IIO index of the trigger.
