[PATCH v9 0/5] soc: aspeed: Add XDMA engine driver

[Eddie James]

This series adds a driver to control the Aspeed XDMA engine embedded in the
AST2500 and AST2600. The XDMA engine performs automatic DMA operations
over PCI-E between the Aspeed SOC (acting as a BMC) and a host processor.

Changes since v8:
 - Use DMA API to allocate memory from reserved region.
 - Fix the driver for the AST2500 by keeping the command queue in kernel
   memory and copying the whole buffer to the reserved memory area before
   starting the operation.
 - Add krefs to the client structure to prevent use-after-free.
 - Switch reset-names binding to "device", "root-complex"
