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>

+* Qualcomm AHCI SATA Controller
+
+SATA nodes are defined to describe on-chip Serial ATA controllers.
+Each SATA controller should have its own node.
+
+Required properties:
+- compatible : compatible list, must contain "generic-ahci"
+- interrupts : <interrupt mapping for SATA IRQ>
+- reg : <registers mapping>
+- phys : Must contain exactly one entry as specified
+ in phy-bindings.txt
+- phy-names : Must be "sata-phy"
+
+Required properties for "qcom,ipq806x-ahci" compatible:
+- clocks : Must contain an entry for each entry in clock-names.
+- clock-names : Shall be:
+ "slave_iface" - Fabric port AHB clock for SATA
+ "iface" - AHB clock
+ "core" - core clock
+ "rxoob" - RX out-of-band clock
+ "pmalive" - Power Module Alive clock
+- assigned-clocks : Shall be:
+ SATA_RXOOB_CLK
+ SATA_PMALIVE_CLK
+- assigned-clock-rates : Shall be:
+ 100Mhz (100000000) for SATA_RXOOB_CLK
+ 100Mhz (100000000) for SATA_PMALIVE_CLK
+
+Example:
+ sata@29000000 {
+ compatible = "qcom,ipq806x-ahci", "generic-ahci";
+ reg = <0x29000000 0x180>;
+
+ interrupts = <0 209 0x0>;
+
+ clocks = <&gcc SFAB_SATA_S_H_CLK>,
+ <&gcc SATA_H_CLK>,
+ <&gcc SATA_A_CLK>,
+ <&gcc SATA_RXOOB_CLK>,
+ <&gcc SATA_PMALIVE_CLK>;
+ clock-names = "slave_iface", "iface", "core",
+ "rxoob", "pmalive";
+ assigned-clocks = <&gcc SATA_RXOOB_CLK>, <&gcc SATA_PMALIVE_CLK>;
+ assigned-clock-rates = <100000000>, <100000000>;
+
+ phys = <&sata_phy>;
+ phy-names = "sata-phy";
+ };
