+* Device tree bindings for the Aspeed XDMA Engine
+
+The XDMA Engine embedded in the AST2500 SOC can perform automatic DMA
+operations over PCI between the AST2500 (acting as a BMC) and a host processor.
+
+Required properties:
+
+ - compatible "aspeed,ast2500-xdma"
+ - reg contains the offset and length of the memory region
+ assigned to the XDMA registers
+ - resets reset specifier for the syscon reset associated with
+ the XDMA engine
+ - interrupts the interrupt associated with the XDMA engine on this
+ platform
+
+Example:
+
+ xdma@1e6e7000 {
+ compatible = "aspeed,ast2500-xdma";
+ reg = <0x1e6e7000 0x100>;
+ resets = <&syscon ASPEED_RESET_XDMA>;
+ interrupts = <6>;
+ };
