MGB4 is a modular frame grabber PCIe card for automotive video interfaces (FPD-Link and GMSL for now). It is based on a Xilinx FPGA and uses their XDMA IP core for DMA transfers. Additionally, Xilinx I2C and SPI IP cores which already have drivers in linux are used in the design. The driver is a quite standard v4l2 driver, with one exception - there are a lot of sysfs options that may/must be set before opening the v4l2 device to adapt the card on a specific signal (see mgb4.rst for details) as the card must be able to work with various signal sources (or displays) that can not be auto-detected. I have run the driver through the v4l2-compliance test suite for both the input and the output and the results look fine to me (I can provide the output if required). The patch requires the new XDMA v8 driver from Xilinx/AMD from the dmaengine mailing list to compile/work: https://www.spinics.net/lists/dmaengine/msg31476.html Changes in v3: * Rebased the DMA transfers part to use the new XDMA driver from Xilinx/AMD Changes in v2: * Completely rewritten the original Xilinx's XDMA driver to meet kernel code standards. * Added all required "to" and "cc" mail addresses.
