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>

+OMAP2+ IOMMU
+
+Required properties:
+- compatible : Should be one of,
+ "ti,omap2-iommu" for OMAP2/OMAP3 IOMMU instances
+ "ti,omap4-iommu" for OMAP4/OMAP5 IOMMU instances
+ "ti,dra7-iommu" for DRA7xx IOMMU instances
+- ti,hwmods : Name of the hwmod associated with the IOMMU instance
+- reg : Address space for the configuration registers
+- interrupts : Interrupt specifier for the IOMMU instance
+
+Optional properties:
+- ti,#tlb-entries : Number of entries in the translation look-aside buffer.
+ Should be either 8 or 32 (default: 32)
+- ti,iommu-bus-err-back : Indicates the IOMMU instance supports throwing
+ back a bus error response on MMU faults.
+
+Example:
+ /* OMAP3 ISP MMU */
+ mmu_isp: mmu@480bd400 {
+ compatible = "ti,omap2-iommu";
+ reg = <0x480bd400 0x80>;
+ interrupts = <24>;
+ ti,hwmods = "mmu_isp";
+ ti,#tlb-entries = <8>;
+ };
