Subject: [PATCH v2] Add Xilinx AXI Video DMA Engine driver
Date: Wed, 22 Jan 2014 22:22:44 +0530	[thread overview]
Message-ID: <1390409565-4200-1-git-send-email-sthokal@xilinx.com> (raw)

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

Use cases:
++++++++++
1. Xilinx Video Targeted Reference design
   http://www.wiki.xilinx.com/Zynq+Base+TRD+14.5
2. Common Display Framework
   http://events.linuxfoundation.org/sites/events/files/slides/20131024-elce.pdf

Regards,
Srikanth
