    +* 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>;
    + };
