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>

+* ARC700 incore Interrupt Controller
+
+ The core interrupt controller provides 32 prioritised interrupts (2 levels)
+ to ARC700 core.
+
+Properties:
+
+- compatible: "snps,arc700-intc"
+- interrupt-controller: This is an interrupt controller.
+- #interrupt-cells: Must be <1>.
+
+ Single Cell "interrupts" property of a device specifies the IRQ number
+ between 0 to 31
+
+ intc accessed via the special ARC AUX register interface, hence "reg" property
+ is not specified.
+
+Example:
+
+ intc: interrupt-controller {
+ compatible = "snps,arc700-intc";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ };
