Subject[PATCH] Add Xilinx AXI Video DMA Engine driver
Date
Hi,

This is the driver for Xilinx AXI Video Direct Memory Access Engine.
It is a soft IP core, which provides high-bandwidth direct memory
access between memory and AXI4-Stream video type target peripherals
including peripherals which support AXI4-Stream Video Protocol. The
core provides efficient two dimensional DMA operations with independent
asynchronous read and write channel operation.

For more information on the IP, please refer to
http://www.xilinx.com/support/documentation/ip_documentation/axi_vdma/v6_1/pg020_axi_vdma.pdf

This patch also provides a test client, which assumes read and write channels
of the core are configured in a back-to-back connection. It transfers
data on the write channel, read and verify the data on the read channel.

Use cases:
++++++++++
1. Xilinx Video Targeted Reference design

2. Common Display Framework
