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>

+Device-Tree bindings for tilcdc DRM generic panel output driver
+
+Required properties:
+ - compatible: value should be "ti,tilcdc,panel".
+ - panel-info: configuration info to configure LCDC correctly for the panel
+ - ac-bias: AC Bias Pin Frequency
+ - ac-bias-intrpt: AC Bias Pin Transitions per Interrupt
+ - dma-burst-sz: DMA burst size
+ - bpp: Bits per pixel
+ - fdd: FIFO DMA Request Delay
+ - sync-edge: Horizontal and Vertical Sync Edge: 0=rising 1=falling
+ - sync-ctrl: Horizontal and Vertical Sync: Control: 0=ignore
+ - raster-order: Raster Data Order Select: 1=Most-to-least 0=Least-to-most
+ - fifo-th: DMA FIFO threshold
+ - display-timings: typical videomode of lcd panel. Multiple video modes
+ can be listed if the panel supports multiple timings, but the 'native-mode'
+ should be the preferred/default resolution. Refer to
+ Documentation/devicetree/bindings/video/display-timing.txt for display
+ timing binding details.
+
+Optional properties:
+- backlight: phandle of the backlight device attached to the panel
+- enable-gpios: GPIO pin to enable or disable the panel
+
+Recommended properties:
+ - pinctrl-names, pinctrl-0: the pincontrol settings to configure
+ muxing properly for pins that connect to TFP410 device
+
+Example:
+
+ /* Settings for CDTech_S035Q01 / LCD3 cape: */
+ lcd3 {
+ compatible = "ti,tilcdc,panel";
+ pinctrl-names = "default";
+ pinctrl-0 = <&bone_lcd3_cape_lcd_pins>;
+ backlight = <&backlight>;
+ enable-gpios = <&gpio3 19 0>;
+
+ panel-info {
+ ac-bias = <255>;
+ ac-bias-intrpt = <0>;
+ dma-burst-sz = <16>;
+ bpp = <16>;
+ fdd = <0x80>;
+ sync-edge = <0>;
+ sync-ctrl = <1>;
+ raster-order = <0>;
+ fifo-th = <0>;
+ };
+ display-timings {
+ native-mode = <&timing0>;
+ timing0: 320x240 {
+ hactive = <320>;
+ vactive = <240>;
+ hback-porch = <21>;
+ hfront-porch = <58>;
+ hsync-len = <47>;
+ vback-porch = <11>;
+ vfront-porch = <23>;
+ vsync-len = <2>;
+ clock-frequency = <8000000>;
+ hsync-active = <0>;
+ vsync-active = <0>;
