+Aspeed AST25XX and AST26XX XDMA Engine
+
+The XDMA Engine embedded in the AST2500 and AST2600 SOCs can perform automatic
+DMA operations over PCI between the SOC (acting as a BMC) and a host processor.
+
+Required properties:
+ - compatible		: must be "aspeed,ast2500-xdma" or
+			  "aspeed,ast2600-xdma"
+ - reg			: contains the address and size of the memory region
+			  associated with the XDMA engine registers
+ - resets		: reset specifier for the syscon reset associated with
+			  the XDMA engine
+ - interrupts-extended	: two interrupt nodes; the first specifies the global
+			  interrupt for the XDMA engine and the second
+			  specifies the PCI-E reset or PERST interrupt.
+
+Example:
+
+    xdma at 1e6e7000 {
+        compatible = "aspeed,ast2500-xdma";
+        reg = <0x1e6e7000 0x100>;
+        resets = <&syscon ASPEED_RESET_XDMA>;
+        interrupts-extended = <&vic 6>, <&scu_ic ASPEED_AST2500_SCU_IC_PCIE_RESET_LO_TO_HI>;
+    };
