Subject: [PATCH 0/2] UIO support for dfl devices

This patchset supports some dfl device drivers written in userspace.

The usage is like:

 # echo dfl_dev.1 > /sys/bus/dfl/drivers/<kernel driver>/unbind
 # echo dfl-uio-pdev > /sys/bus/dfl/devices/dfl_dev.1/driver_override
 # echo dfl_dev.1 > /sys/bus/dfl/drivers_probe


Xu Yilun (2):
  fpga: dfl: add driver_override support
  fpga: dfl: add the userspace I/O device support for DFL devices
