[PATCH v2] Add Xilinx AXI Video DMA Engine driver

From: Srikanth Thokala
Date: Wed Jan 22 2014 - 11:58:09 EST


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

Use cases:
1. Xilinx Video Targeted Reference design
2. Common Display Framework
