dma: Add Xilinx AXI Video Direct Memory Access Engine driver support 2014-04-30T05:14:13+00:00 Srikanth Thokala sthokal@xilinx.com 2014-04-23T14:53:26+00:00 9cd4360de6090a6daf7fbe024e34953f2ae60ef2 This is the driver for the AXI Video Direct Memory Access (AXI VDMA) core, which is a soft Xilinx IP core that provides high- bandwidth direct memory access between memory and AXI4-Stream type video target peripherals. The core provides efficient two dimensional DMA operations with independent asynchronous read and write channel operation. This module works on Zynq (ARM Based SoC) and Microblaze platforms.
