This avoids having to write/change a vfio-specific reset driver for each and every device to be passed-through to a guest. This has been tested using the R-Car Gen3 GPIO Pass-Through Prototype posted last week: the GPIO module is reset before QEMU opens the vfio device, and reset again after QEMU has released it, as can be witnessed by the LEDs on the Salvator-XS board. Thanks for your comments!
