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:// 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/.

+Device-Tree Bindings for a PPS Signal on GPIO
+These properties describe a PPS (pulse-per-second) signal connected to
+a GPIO pin.
+Required properties:
+- compatible: should be "pps-gpio"
+- gpios: one PPS GPIO in the format described by ../gpio/gpio.txt
+Optional properties:
+- assert-falling-edge: when present, assert is indicated by a falling edge
+ (instead of by a rising edge)
+ pps {
+ compatible = "pps-gpio";
+ gpios = <&gpio2 6 0>;
+ assert-falling-edge;
+ };
