Dan Carpenter 550f45bc83 [media] v4l: xilinx: harmless buffer overflow
My static checker warns that the name of the port can be 15 characters
when you consider the NUL terminator and that's one more than the 14
characters in name[].  Maybe it's an off-by-one?

It's unlikely that we hit the limit and even if we do the overflow will
only affect one of the two bytes of padding so it's harmless.  Still
let's fix it and also change the sprintf() to snprintf().

Geert Uytterhoeven 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.

Laurent Pinchart 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.

Laurent Pinchart 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.
