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/platform/devices/ci_hdrc.0/inputs/a_bus_req
+Date: Feb 2014
+Contact: Li Jun <b47624@freescale.com>
+Description:
+ Can be set and read.
+ Set a_bus_req(A-device bus request) input to be 1 if
+ the application running on the A-device wants to use the bus,
+ and to be 0 when the application no longer wants to use
+ the bus(or wants to work as peripheral). a_bus_req can also
+ be set to 1 by kernel in response to remote wakeup signaling
+ from the B-device, the A-device should decide to resume the bus.
+
+ Valid values are "1" and "0".
+
+ Reading: returns 1 if the application running on the A-device
+ is using the bus as host role, otherwise 0.

+Date: Feb 2014
+Contact: Li Jun <b47624@freescale.com>
+Description:
+ Can be set and read
+ The a_bus_drop(A-device bus drop) input is 1 when the
+ application running on the A-device wants to power down
+ the bus, and is 0 otherwise, When a_bus_drop is 1, then
+ the a_bus_req shall be 0.
+
+ Valid values are "1" and "0".
+
+ Reading: returns 1 if the bus is off(vbus is turned off) by
+ A-device, otherwise 0.

+Date: Feb 2014
+Contact: Li Jun <b47624@freescale.com>
+Description:
+ Can be set and read.
+ The b_bus_req(B-device bus request) input is 1 during the time
+ that the application running on the B-device wants to use the
+ bus as host, and is 0 when the application no longer wants to
+ work as host and decides to switch back to be peripheral.
+
+ Valid values are "1" and "0".
+
+ Reading: returns if the application running on the B device
+ is using the bus as host role, otherwise 0.

+Date: Feb 2014
+Contact: Li Jun <b47624@freescale.com>
+Description:
+ Only can be set.
+ The a_clr_err(A-device Vbus error clear) input is used to clear
+ vbus error, then A-device will power down the bus.
+
+ Valid value is "1"
