+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>;
+ };
