Subject: [PATCH] drm/vc4: tests: Add unit test suite for the PV muxing
|
|
|
|
The HVS to PixelValve muxing code is fairly error prone and has a bunch
|
|
of arbitrary constraints due to the hardware setup.
|
|
|
|
Let's create a test suite that makes sure that the possible combinations
|
|
work and the invalid ones don't.
