+The Octeon DMA Engine transfers between the Boot Bus and main memory.
+The DMA Engine will be referred to by phandle by any device that is
+connected to it.

+
+ Compatibility with all cn52XX, cn56XX and cn6XXX SOCs.
+
+- reg: The base address of the DMA Engine's register bank.
+
+- interrupts: A single interrupt specifier.
+
+Example:
+ dma0: dma-engine@1180000000100 {
+ compatible = "cavium,octeon-5750-bootbus-dma";
+ reg = <0x11800 0x00000100 0x0 0x8>;
+ interrupts = <0 63>;
