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>

+OMAP PRCM bindings
+
+Power Reset and Clock Manager lists the device clocks and clockdomains under
+a DT hierarchy. Each TI SoC can have multiple PRCM entities listed for it,
+each describing one module and the clock hierarchy under it. see [1] for
+documentation about the individual clock/clockdomain nodes.
+
+[1] Documentation/devicetree/bindings/clock/ti/*
+
+Required properties:
+- compatible: Must be one of:
+ "ti,am3-prcm"
+ "ti,am4-prcm"
+ "ti,omap2-prcm"
+ "ti,omap3-prm"
+ "ti,omap3-cm"
+ "ti,omap4-cm1"
+ "ti,omap4-prm"
+ "ti,omap4-cm2"
+ "ti,omap4-scrm"
+ "ti,omap5-prm"
+ "ti,omap5-cm-core-aon"
+ "ti,omap5-scrm"
+ "ti,omap5-cm-core"
+ "ti,dra7-prm"
+ "ti,dra7-cm-core-aon"
+ "ti,dra7-cm-core"
+ "ti,dm814-prcm"
+ "ti,dm816-prcm"
+- reg: Contains PRCM module register address range
+ (base address and length)
+- clocks: clocks for this module
+- clockdomains: clockdomains for this module
+
+Example:
+
+cm: cm@48004000 {
+ compatible = "ti,omap3-cm";
+ reg = <0x48004000 0x4000>;
+
+ cm_clocks: clocks {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ };
+
+ cm_clockdomains: clockdomains {
+ };
+}
+
+&cm_clocks {
+ omap2_32k_fck: omap_32k_fck {
+ #clock-cells = <0>;
+ compatible = "fixed-clock";
+ clock-frequency = <32768>;
+ };
+};
+
+&cm_clockdomains {
+ core_l3_clkdm: core_l3_clkdm {
+ compatible = "ti,clockdomain";
+ clocks = <&sdrc_ick>;
+ };
+};
