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>

+Kernel driver ltc4151
+=====================
+
+Supported chips:
+ * Linear Technology LTC4151
+ Prefix: 'ltc4151'
+ Addresses scanned: -
+ Datasheet:
+ http://www.linear.com/docs/Datasheet/4151fc.pdf
+
+Author: Per Dalen <per.dalen@appeartv.com>
+
+
+Description
+-----------
+
+The LTC4151 is a High Voltage I2C Current and Voltage Monitor.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for LTC4151 devices, since there is no register
+which can be safely used to identify the chip. You will have to instantiate
+the devices explicitly.
+
+Example: the following will load the driver for an LTC4151 at address 0x6f
+on I2C bus #0:
+# modprobe ltc4151
+# echo ltc4151 0x6f > /sys/bus/i2c/devices/i2c-0/new_device
+
+
+Sysfs entries
+-------------
+
+Voltage readings provided by this driver are reported as obtained from the ADIN
+and VIN registers.
+
+Current reading provided by this driver is reported as obtained from the Current
+Sense register. The reported value assumes that a 1 mOhm sense resistor is
+installed.
