Michal Simek	29a4bb1431	dma: xilinx: Remove .owner field for driver ... There is no need to init .owner field. Based on the patch from Peter Griffin <peter.griffin@linaro.org> "mmc: remove .owner field for drivers using module_platform_driver" This patch removes the superflous .owner field for drivers which use the module_platform_driver API, as this is overriden in platform_driver_register anyway."

Srikanth Thokala	9cd4360de6	dma: Add Xilinx AXI Video Direct Memory Access Engine driver support ... 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.
