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>

+DT bindings for Xilinx video IP cores
+-------------------------------------
+
+Xilinx video IP cores process video streams by acting as video sinks and/or
+sources. They are connected by links through their input and output ports,
+creating a video pipeline.
+
+Each video IP core is represented by an AMBA bus child node in the device
+tree using bindings documented in this directory. Connections between the IP
+cores are represented as defined in ../video-interfaces.txt.
+
+The whole pipeline is represented by an AMBA bus child node in the device
+tree using bindings documented in ./xlnx,video.txt.
+
+Common properties
+-----------------
+
+The following properties are common to all Xilinx video IP cores.
+
+- xlnx,video-format: This property represents a video format transmitted on an
+ AXI bus between video IP cores, using its VF code as defined in "AXI4-Stream
+ Video IP and System Design Guide" [UG934]. How the format relates to the IP
+ core is decribed in the IP core bindings documentation.
+
+- xlnx,video-width: This property qualifies the video format with the sample
+ width expressed as a number of bits per pixel component. All components must
+ use the same width.
+
+- xlnx,cfa-pattern: When the video format is set to Mono/Sensor, this property
+ describes the sensor's color filter array pattern. Supported values are
+ "bggr", "gbrg", "grbg", "rggb" and "mono". If not specified, the pattern
+ defaults to "mono".
