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/.

+Xilinx XADC device driver
+
+This binding document describes the bindings for both of them since the
+bindings are very similar. The Xilinx XADC is a ADC that can be found in the
+series 7 FPGAs from Xilinx. The XADC has a DRP interface for communication.
+Currently two different frontends for the DRP interface exist. One that is only
+available on the ZYNQ family as a hardmacro in the SoC portion of the ZYNQ. The
+other one is available on all series 7 platforms and is a softmacro with a AXI
+interface. This binding document describes the bindings for both of them since
+the bindings are very similar.
+
+Required properties:
+ - compatible: Should be one of
+ * "xlnx,zynq-xadc-1.00.a": When using the ZYNQ device
+ configuration interface to interface to the XADC hardmacro.
+ * "xlnx,axi-xadc-1.00.a": When using the axi-xadc pcore to
+ interface to the XADC hardmacro.
+ - reg: Address and length of the register set for the device
+ - interrupts: Interrupt for the XADC control interface.
+ - clocks: When using the ZYNQ this must be the ZYNQ PCAP clock,
+ when using the AXI-XADC pcore this must be the clock that provides the
+ clock to the AXI bus interface of the core.
+
+Optional properties:
+ - interrupt-parent: phandle to the parent interrupt controller
+ - xlnx,external-mux:
+ * "none": No external multiplexer is used, this is the default
+ if the property is omitted.
+ * "single": External multiplexer mode is used with one
+ multiplexer.
+ * "dual": External multiplexer mode is used with two
+ multiplexers for simultaneous sampling.
+ - xlnx,external-mux-channel: Configures which pair of pins is used to
+ sample data in external mux mode.
+ Valid values for single external multiplexer mode are:
+ 0: VP/VN
+ 1: VAUXP[0]/VAUXN[0]
+ 2: VAUXP[1]/VAUXN[1]
+ ...
+ 16: VAUXP[15]/VAUXN[15]
+ Valid values for dual external multiplexer mode are:
+ 1: VAUXP[0]/VAUXN[0] - VAUXP[8]/VAUXN[8]
+ 2: VAUXP[1]/VAUXN[1] - VAUXP[9]/VAUXN[9]
+ ...
+ 8: VAUXP[7]/VAUXN[7] - VAUXP[15]/VAUXN[15]
+
+ This property needs to be present if the device is configured for
+ external multiplexer mode (either single or dual). If the device is
+ not using external multiplexer mode the property is ignored.
+ - xnlx,channels: List of external channels that are connected to the ADC
+ Required properties:
+ * #address-cells: Should be 1.
+ * #size-cells: Should be 0.
+
+ The child nodes of this node represent the external channels which are
+ connected to the ADC. If the property is no present no external
+ channels will be assumed to be connected.
+
+ Each child node represents one channel and has the following
+ properties:
+ Required properties:
+ * reg: Pair of pins the the channel is connected to.
+ 0: VP/VN
+ 1: VAUXP[0]/VAUXN[0]
+ 2: VAUXP[1]/VAUXN[1]
+ ...
+ 16: VAUXP[15]/VAUXN[15]
+ Note each channel number should only be used at most
+ once.
+ Optional properties:
+ * xlnx,bipolar: If set the channel is used in bipolar
+ mode.
+
+
+Examples:

+This binding is derived from clock bindings, and based on suggestions
+from Lars-Peter Clausen [1].
+
+Sources of IIO channels can be represented by any node in the device
+tree. Those nodes are designated as IIO providers. IIO consumer
+nodes use a phandle and IIO specifier pair to connect IIO provider
+outputs to IIO inputs. Similar to the gpio specifiers, an IIO
+specifier is an array of one or more cells identifying the IIO
+output on a device. The length of an IIO specifier is defined by the
+value of a #io-channel-cells property in the IIO provider node.
+
+[1] http://marc.info/?l=linux-iio&m=135902119507483&w=2
+
+==IIO providers==
+
+Required properties:
+#io-channel-cells: Number of cells in an IIO specifier; Typically 0 for nodes
+ with a single IIO output and 1 for nodes with multiple
+ IIO outputs.
+
+Example for a simple configuration with no trigger:
+
+ adc: voltage-sensor@35 {
+ compatible = "maxim,max1139";
+ reg = <0x35>;
+ #io-channel-cells = <1>;
+ };
+
+Example for a configuration with trigger:
+
+ adc@35 {
+ compatible = "some-vendor,some-adc";
+ reg = <0x35>;
+
+ adc1: iio-device@0 {
+ #io-channel-cells = <1>;
+ /* other properties */
+ };
+ adc2: iio-device@1 {
+ #io-channel-cells = <1>;
+ /* other properties */
+ };
+ };
+
+==IIO consumers==
+
+Required properties:
+io-channels: List of phandle and IIO specifier pairs, one pair
+ for each IIO input to the device. Note: if the
+ IIO provider specifies '0' for #io-channel-cells,
+ then only the phandle portion of the pair will appear.
+
+Optional properties:
+io-channel-names:
+ List of IIO input name strings sorted in the same
+ order as the io-channels property. Consumers drivers
+ will use io-channel-names to match IIO input names
+ with IIO specifiers.
+io-channel-ranges:
+ Empty property indicating that child nodes can inherit named
+ IIO channels from this node. Useful for bus nodes to provide
+ and IIO channel to their children.
+
+For example:
+
+ device {
+ io-channels = <&adc 1>, <&ref 0>;
+ io-channel-names = "vcc", "vdd";
+ };
+
+This represents a device with two IIO inputs, named "vcc" and "vdd".
+The vcc channel is connected to output 1 of the &adc device, and the
+vdd channel is connected to output 0 of the &ref device.
+
+==Example==
+
+ adc: max1139@35 {
+ compatible = "maxim,max1139";
+ reg = <0x35>;
+ #io-channel-cells = <1>;
+ };
+
+ ...
+
+ iio_hwmon {
+ compatible = "iio-hwmon";
+ io-channels = <&adc 0>, <&adc 1>, <&adc 2>,

+ <&adc 6>, <&adc 7>, <&adc 8>,
