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>

+STMicroelectronics SoC DWMAC glue layer controller
+
+This file documents differences between the core properties in
+Documentation/devicetree/bindings/net/stmmac.txt
+and what is needed on STi platforms to program the stmmac glue logic.
+
+The device node has following properties.
+
+Required properties:
+ - compatible : Can be "st,stih415-dwmac", "st,stih416-dwmac",
+ "st,stih407-dwmac", "st,stid127-dwmac".
+ - st,syscon : Should be phandle/offset pair. The phandle to the syscon node which
+ encompases the glue register, and the offset of the control register.
+ - st,gmac_en: this is to enable the gmac into a dedicated sysctl control
+ register available on STiH407 SoC.
+ - pinctrl-0: pin-control for all the MII mode supported.
+
+Optional properties:
+ - resets : phandle pointing to the system reset controller with correct
+ reset line index for ethernet reset.
+ - st,ext-phyclk: valid only for RMII where PHY can generate 50MHz clock or
+ MAC can generate it.
+ - st,tx-retime-src: This specifies which clk is wired up to the mac for
+ retimeing tx lines. This is totally board dependent and can take one of the
+ posssible values from "txclk", "clk_125" or "clkgen".
+ If not passed, the internal clock will be used by default.
+ - sti-ethclk: this is the phy clock.
+ - sti-clkconf: this is an extra sysconfig register, available in new SoCs,
+ to program the clk retiming.
+ - st,gmac_en: to enable the GMAC, this only is present in some SoCs; e.g.
+ STiH407.
+
+Example:
+
+ethernet0: dwmac@9630000 {
+ device_type = "network";
+ status = "disabled";
+ compatible = "st,stih407-dwmac", "snps,dwmac", "snps,dwmac-3.710";
+ reg = <0x9630000 0x8000>;
+ reg-names = "stmmaceth";
+
+ st,syscon = <&syscfg_sbc_reg 0x80>;
+ st,gmac_en;
+ resets = <&softreset STIH407_ETH1_SOFTRESET>;
+ reset-names = "stmmaceth";
+
+ interrupts = <GIC_SPI 98 IRQ_TYPE_NONE>,
+ <GIC_SPI 99 IRQ_TYPE_NONE>,
+ <GIC_SPI 100 IRQ_TYPE_NONE>;
+ interrupt-names = "macirq", "eth_wake_irq", "eth_lpi";
+
+ snps,pbl = <32>;
+ snps,mixed-burst;
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_rgmii1>;
+
+ clock-names = "stmmaceth", "sti-ethclk";
+ clocks = <&CLK_S_C0_FLEXGEN CLK_EXT2F_A9>,
+ <&CLK_S_C0_FLEXGEN CLK_ETH_PHY>;
