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. Changes in v10: * Use propper locks/is_busy functions when accessing the video devices in the sysfs callbacks. * Fixed issues found by the sparse/smatch tools. Changes in v9: * Renamed all sysfs show/store functions using the propper naming convention. * Now using device_add_groups() when initializing the sysfs properties. * Fixed build without debugfs support. * Fixed documentation (vsync/hsync) + added default values where applicable. * Fixed the rest of minor issues from v8 review. Changes in v8: * Fixed broken video buffer size computation. * Fixed switched I2C deserializers addresses. * Do not depend on hwmon. Changes in v7: * Now using hwmon for FPGA temperature reporting. * Now using VIDIOC_S_FMT and v4l2_pix_format.bytesperline for setting the alignment. * Removed the magic sleep when loading the i2c/spi adapter modules (solved by request_module() calls with propper - "platform:" prefixed - module names). * Now properly reporting all the timings info in the VIDIOC_G_DV_TIMINGS ioctls. * Updated the documentation. * Minor fixes as discussed in the v6 review. * Added debugfs access to the FPGA registers. Changes in v6: * Rebased to current master that includes the Xilinx XDMA driver. Changes in v5: * Removed unused includes Changes in v4: * Redesigned the signal change handling logic. Now using the propper timings API in the video input driver and a propper open() syscall check/logic in the video output driver. * Fixed all minor issues from v3 review. * 'checkpatch.pl --strict' used for checking the code. 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. ===== v4l2-compliance results - input ===== v4l2-compliance 1.24.1, 64 bits, 64-bit time_t Compliance test for mgb4 device /dev/video0: Driver Info:
