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>

+* Broadcom Keypad Controller device tree bindings
+
+Broadcom Keypad controller is used to interface a SoC with a matrix-type
+keypad device. The keypad controller supports multiple row and column lines.
+A key can be placed at each intersection of a unique row and a unique column.
+The keypad controller can sense a key-press and key-release and report the
+event using a interrupt to the cpu.
+
+This binding is based on the matrix-keymap binding with the following
+changes:
+
+keypad,num-rows and keypad,num-columns are required.
+
+Required SoC Specific Properties:
+- compatible: should be "brcm,bcm-keypad"

+Input: sysrq reset sequence
+
+A simple binding to represent a set of keys as described in
+include/uapi/linux/input.h. This is to communicate a sequence of keys to the
+sysrq driver. Upon holding the keys for a specified amount of time (if
+specified) the system is sync'ed and reset.
+
+Key sequences are global to the system but all the keys in a set must be coming
+from the same input device.
+
+The /chosen node should contain a 'linux,sysrq-reset-seq' child node to define
+a set of keys.
+
+Required property:
+sysrq-reset-seq: array of Linux keycodes, one keycode per cell.
+
+Optional property:
+timeout-ms: duration keys must be pressed together in milliseconds before
+generating a sysrq. If omitted the system is rebooted immediately when a valid
+sequence has been recognized.
+
+Example:
+
+ chosen {
+                linux,sysrq-reset-seq {
+                        keyset = <0x03
+                                  0x04

+                        timeout-ms = <3000>;
+                };
+         };
+
+Would represent KEY_2, KEY_3 and KEY_9.

+* Samsung's Keypad Controller device tree bindings
+
+Samsung's Keypad controller is used to interface a SoC with a matrix-type
+keypad device. The keypad controller supports multiple row and column lines.
+A key can be placed at each intersection of a unique row and a unique column.
+The keypad controller can sense a key-press and key-release and report the
+event using a interrupt to the cpu.
+
+Required SoC Specific Properties:
+- compatible: should be one of the following
+  - "samsung,s3c6410-keypad": For controllers compatible with s3c6410 keypad
+    controller.
+  - "samsung,s5pv210-keypad": For controllers compatible with s5pv210 keypad

+
+- reg: physical base address of the controller and length of memory mapped
+  region.
+
+- interrupts: The interrupt number to the cpu.
+
+Required Board Specific Properties:
+- samsung,keypad-num-rows: Number of row lines connected to the keypad
+  controller.
+
+- samsung,keypad-num-columns: Number of column lines connected to the
+  keypad controller.
+
+- Keys represented as child nodes: Each key connected to the keypad
+  controller is represented as a child node to the keypad controller
+  device node and should include the following properties.
+  - keypad,row: the row number to which the key is connected.
+  - keypad,column: the column number to which the key is connected.
+  - linux,code: the key-code to be reported when the key is pressed
+    and released.
+
+- pinctrl-0: Should specify pin control groups used for this controller.
+- pinctrl-names: Should contain only one value - "default".
+
+Optional Properties specific to linux:
+- linux,keypad-no-autorepeat: do no enable autorepeat feature.
+- linux,keypad-wakeup: use any event on keypad as wakeup event.

+Texas Instruments Palmas family power button module
+
+This module is part of the Palmas family of PMICs. For more details
+about the whole chip see:
+Documentation/devicetree/bindings/mfd/palmas.txt.
+
+This module provides a simple power button event via an Interrupt.
+
+Required properties:
+- compatible: should be one of the following
+   - "ti,palmas-pwrbutton": For Palmas compatible power on button
+- interrupt-parent: Parent interrupt device, must be handle of palmas node.
+- interrupts: Interrupt number of power button submodule on device.
+
+Optional Properties:
+
+- ti,palmas-long-press-seconds: Duration in seconds which the power
+  button should be kept pressed for Palmas to power off automatically.
+  NOTE: This depends on OTP support and POWERHOLD signal configuration
+  on platform. Valid values are 6, 8, 10 and 12.
+- ti,palmas-pwron-debounce-milli-seconds: Duration in milliseconds
+  which the power button should be kept pressed for Palmas to register
+  a press for debouncing purposes. NOTE: This depends on specific
+  Palmas variation capability. Valid values are 15, 100, 500 and 1000.
+
+Example:
+
+&palmas {
+	palmas_pwr_button: pwrbutton {

+FocalTech EDT-FT5x06 Polytouch driver
+=====================================
+
+There are 3 variants of the chip for various touch panel sizes
+FT5206GE1  2.8" .. 3.8"
+FT5306DE4  4.3" .. 7"
+FT5406EE8  7"   .. 8.9"
+
+The software interface is identical for all those chips, so that
+currently there is no need for the driver to distinguish between the
+different chips. Nevertheless distinct compatible strings are used so
+that a distinction can be added if necessary without changing the DT
+bindings.
+
+
+Required properties:
+ - compatible:  "edt,edt-ft5206"
+           or:  "edt,edt-ft5306"
+           or:  "edt,edt-ft5406"
+
+ - reg:         I2C slave address of the chip (0x38)
+ - interrupt-parent: a phandle pointing to the interrupt controller
+                     serving the interrupt for this chip
+ - interrupts:       interrupt specification for the touchdetect
+                     interrupt
+
+Optional properties:
+ - reset-gpios: GPIO specification for the RESET input
+ - wake-gpios:  GPIO specification for the WAKE input
+
+ - pinctrl-names: should be "default"
+ - pinctrl-0:   a phandle pointing to the pin settings for the
+                control gpios
+
+ - threshold:   allows setting the "click"-threshold in the range
+                from 20 to 80.
+
+ - gain:        allows setting the sensitivity in the range from 0 to
+                31. Note that lower values indicate higher
+                sensitivity.
+
+ - offset:      allows setting the edge compensation in the range from
+                0 to 31.
+
+Example:
+	polytouch: edt-ft5x06@38 {

+* TI - TSC ADC (Touschscreen and analog digital converter)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Required properties:
+- child "tsc"
+	ti,wires: Wires refer to application modes i.e. 4/5/8 wire touchscreen
+		  support on the platform.
+	ti,x-plate-resistance: X plate resistance
+	ti,coordinate-readouts: The sequencer supports a total of 16
+				programmable steps each step is used to
+				read a single coordinate. A single
+                                readout is enough but multiple reads can
+				increase the quality.
+				A value of 5 means, 5 reads for X, 5 for
+				Y and 2 for Z (always). This utilises 12
+				of the 16 software steps available. The
+				remaining 4 can be used by the ADC.
+	ti,wire-config: Different boards could have a different order for
+			connecting wires on touchscreen. We need to provide an
+			8 bit number where in the 1st four bits represent the
+			analog lines and the next 4 bits represent positive/
+			negative terminal on that input line. Notations to
+			represent the input lines and terminals resoectively
+			is as follows:
+			AIN0 = 0, AIN1 = 1 and so on till AIN7 = 7.
+			XP  = 0, XN = 1, YP = 2, YN = 3.
+- child "adc"
+	ti,adc-channels: List of analog inputs available for ADC.
+			 AIN0 = 0, AIN1 = 1 and so on till AIN7 = 7.
+
+Optional properties:
+- child "tsc"
+	ti,charge-delay: Length of touch screen charge delay step in terms of
+			 ADC clock cycles. Charge delay value should be large
+			 in order to avoid false pen-up events. This value
+			 effects the overall sampling speed, hence need to be
+			 kept as low as possible, while avoiding false pen-up
+			 event. Start from a lower value, say 0x400, and
+			 increase value until false pen-up events are avoided.
+			 The pen-up detection happens immediately after the
+			 charge step, so this does in fact function as a
+			 hardware knob for adjusting the amount of "settling
+			 time".
+
+Example:
+	tscadc: tscadc@44e0d000 {
+		compatible = "ti,am3359-tscadc";
+		tsc {

+			ti,x-plate-resistance = <200>;
