KUnit Tests

===========



The VC4 Driver uses KUnit to perform driver-specific unit and

integration tests.



These tests are using a mock driver and can be ran using the

command::

	./tools/testing/kunit/kunit.py run \

		--kunitconfig=drivers/gpu/drm/vc4/tests/.kunitconfig \

		--cross_compile aarch64-linux-gnu- --arch arm64



Parts of the driver that are currently covered by tests are:

 * The HVS to PixelValve dynamic FIFO assignment, for the BCM2835-7

   and BCM2711.
