Add devicetree source files as of Linux-3.15-rc2

This adds the Linux dts files to barebox. The dts files are
generated from Ian Campbells device-tree-rebasing.git:

git://xenbits.xen.org/people/ianc/device-tree-rebasing.git

The dts are found in dts/ in the barebox repository and
will be updated from upstream regularly, probably for each upstream
-rc.

To keep the synchronization with upstream easy no changes to
the original files are allowed under dts/. Instead changes to
upstream dts files will be done using overlays in arch/$ARCH/dts/.

+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 {
+		compatible = "edt,edt-ft5406", "edt,edt-ft5x06";
+		reg = <0x38>;
+		pinctrl-names = "default";

+		interrupt-parent = <&gpio2>;
+		interrupts = <5 0>;

+* 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.
