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/.

+* Freescale IMX35 IOMUX Controller
+
+Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
+and usage.
+
+Required properties:
+- compatible: "fsl,imx35-iomuxc"
+- fsl,pins: two integers array, represents a group of pins mux and config
+ setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
+ pin working on a specific function, CONFIG is the pad setting value like
+ pull-up for this pin. Please refer to imx35 datasheet for the valid pad
+ config settings.
+
+CONFIG bits definition:
+PAD_CTL_DRIVE_VOLAGAGE_18 (1 << 13)
+PAD_CTL_DRIVE_VOLAGAGE_33 (0 << 13)
+PAD_CTL_HYS (1 << 8)
+PAD_CTL_PKE (1 << 7)
+PAD_CTL_PUE (1 << 6)
+PAD_CTL_PUS_100K_DOWN (0 << 4)
+PAD_CTL_PUS_47K_UP (1 << 4)
