bf7096c664 [media] v4l: xilinx: VIDEO_XILINX should depend on HAS_DMA
If NO_DMA=y:

    warning: (VIDEO_XILINX && VIDEO_DM365_VPFE && VIDEO_DT3155 && VIDEO_OMAP4) selects VIDEOBUF2_DMA_CONTIG which has unmet direct dependencies (MEDIA_SUPPORT && HAS_DMA)

    media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_mmap’:
    media/v4l2-core/videobuf2-dma-contig.c:207: error: implicit declaration of function ‘dma_mmap_coherent’
    media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_get_base_sgt’:
    media/v4l2-core/videobuf2-dma-contig.c:390: error: implicit declaration of function ‘dma_get_sgtable’

VIDEO_XILINX selects VIDEOBUF2_DMA_CONTIG, which bypasses its dependency
on HAS_DMA.  Make VIDEO_XILINX depend on HAS_DMA to fix this.

a5562f65b1 [media] v4l: xilinx: Add Test Pattern Generator driver
The TPG generates multiple static or dynamic test patterns. The driver
currently hardcodes the pattern to the moving box pattern.

df3305156f [media] v4l: xilinx: Add Xilinx Video IP core
Xilinx platforms have no hardwired video capture or video processing
interface. Users create capture and memory to memory processing
pipelines in the FPGA fabric to suit their particular needs, by
instantiating video IP cores from a large library.

The Xilinx Video IP core is a framework that models a video pipeline
described in the device tree and expose the pipeline to userspace
through the media controller and V4L2 APIs.
