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>

+* Renesas R-Mobile/R-Car Timer Unit (TMU)
+
+The TMU is a 32-bit timer/counter with configurable clock inputs and
+programmable compare match.
+
+Channels share hardware resources but their counter and compare match value
+are independent. The TMU hardware supports up to three channels.
+
+Required Properties:
+
+ - compatible: must contain one or more of the following:
+ - "renesas,tmu-r8a7740" for the r8a7740 TMU
+ - "renesas,tmu-r8a7778" for the r8a7778 TMU
+ - "renesas,tmu-r8a7779" for the r8a7779 TMU
+ - "renesas,tmu" for any TMU.
+ This is a fallback for the above renesas,tmu-* entries
+
+ - reg: base address and length of the registers block for the timer module.
+
+ - interrupts: interrupt-specifier for the timer, one per channel.
+
+ - clocks: a list of phandle + clock-specifier pairs, one for each entry
+ in clock-names.
+ - clock-names: must contain "fck" for the functional clock.
+
+Optional Properties:
+
+ - #renesas,channels: number of channels implemented by the timer, must be 2
+ or 3 (if not specified the value defaults to 3).
+
+
+Example: R8A7779 (R-Car H1) TMU0 node
+
+ tmu0: timer@ffd80000 {
+ compatible = "renesas,tmu-r8a7779", "renesas,tmu";
+ reg = <0xffd80000 0x30>;
+ interrupts = <0 32 IRQ_TYPE_LEVEL_HIGH>,
+ <0 33 IRQ_TYPE_LEVEL_HIGH>,
+ <0 34 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&mstp0_clks R8A7779_CLK_TMU0>;
+ clock-names = "fck";
+
+ #renesas,channels = <3>;
+ };
