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>

+What: /sys/bus/i2c/devices/<busnum>-<devaddr>/pressure0_input
+Date: June 2010
+Contact: Christoph Mair <christoph.mair@gmail.com>
+Description: Start a pressure measurement and read the result. Values
+ represent the ambient air pressure in pascal (0.01 millibar).
+
+ Reading: returns the current air pressure.
+
+
+What: /sys/bus/i2c/devices/<busnum>-<devaddr>/temp0_input
+Date: June 2010
+Contact: Christoph Mair <christoph.mair@gmail.com>
+Description: Measure the ambient temperature. The returned value represents
+ the ambient temperature in units of 0.1 degree celsius.
+
+ Reading: returns the current temperature.
+
+
+What: /sys/bus/i2c/devices/<busnum>-<devaddr>/oversampling
+Date: June 2010
+Contact: Christoph Mair <christoph.mair@gmail.com>
+Description: Tell the bmp085 to use more samples to calculate a pressure
+ value. When writing to this file the chip will use 2^x samples
+ to calculate the next pressure value with x being the value
+ written. Using this feature will decrease RMS noise and
+ increase the measurement time.
+
+ Reading: returns the current oversampling setting.
+
+ Writing: sets a new oversampling setting.
+ Accepted values: 0..3.
