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/.

+* Marvell XOR engines
+
+Required properties:
+- compatible: Should be "marvell,orion-xor"
+- reg: Should contain registers location and length (two sets)
+ the first set is the low registers, the second set the high
+ registers for the XOR engine.
+- clocks: pointer to the reference clock
+
+The DT node must also contains sub-nodes for each XOR channel that the
+XOR engine has. Those sub-nodes have the following required
+properties:
+- interrupts: interrupt of the XOR channel
+
+And the following optional properties:
+- dmacap,memcpy to indicate that the XOR channel is capable of memcpy operations
+- dmacap,memset to indicate that the XOR channel is capable of memset operations
+- dmacap,xor to indicate that the XOR channel is capable of xor operations
+
+Example:
+
+xor@d0060900 {
+ compatible = "marvell,orion-xor";
+ reg = <0xd0060900 0x100
+ 0xd0060b00 0x100>;
+ clocks = <&coreclk 0>;
+ status = "okay";
+
+ xor00 {
+ interrupts = <51>;
+ dmacap,memcpy;
+ dmacap,xor;
+ };
+ xor01 {
+ interrupts = <52>;
+ dmacap,memcpy;
+ dmacap,xor;
+ dmacap,memset;
+ };
+};
