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>

+* Texas Instruments Davinci EMAC
+
+This file provides information, what the device node
+for the davinci_emac interface contains.
+
+Required properties:
+- compatible: "ti,davinci-dm6467-emac", "ti,am3517-emac" or
+ "ti,dm816-emac"
+- reg: Offset and length of the register set for the device
+- ti,davinci-ctrl-reg-offset: offset to control register
+- ti,davinci-ctrl-mod-reg-offset: offset to control module register
+- ti,davinci-ctrl-ram-offset: offset to control module ram
+- ti,davinci-ctrl-ram-size: size of control module ram
+- interrupts: interrupt mapping for the davinci emac interrupts sources:
+ 4 sources: <Receive Threshold Interrupt
+ Receive Interrupt
+ Transmit Interrupt
+ Miscellaneous Interrupt>
+
+Optional properties:
+- phy-handle: See ethernet.txt file in the same directory.
+ If absent, davinci_emac driver defaults to 100/FULL.
+- ti,davinci-rmii-en: 1 byte, 1 means use RMII
+- ti,davinci-no-bd-ram: boolean, does EMAC have BD RAM?
+
+Example (enbw_cmc board):
+ eth0: emac@1e20000 {
+ compatible = "ti,davinci-dm6467-emac";
+ reg = <0x220000 0x4000>;
+ ti,davinci-ctrl-reg-offset = <0x3000>;
+ ti,davinci-ctrl-mod-reg-offset = <0x2000>;
+ ti,davinci-ctrl-ram-offset = <0>;
+ ti,davinci-ctrl-ram-size = <0x2000>;
+ local-mac-address = [ 00 00 00 00 00 00 ];
+ interrupts = <33
+ 34
+ 35
+ 36
+ >;
+ interrupt-parent = <&intc>;
+ };
