I could think of below test aspects for this series
1. Suspend Resume
2. Concurrency test
3. Module load -> video usecase -> module unload -> module load -> video
usecase. This would ensure video firmware is reloaded and functional.
4. Video playback and encode for all supported resolution and codecs.
5. In general, video playback with more test content.

I would be testing the series with stability test suite on CrOS. That would be
either on sc7180 or sc7280 setup.

Konrad, you can post the new version as one patch needs to be dropped. Test can
be done on the new version. There are few patches in the series pending review,
which can be done in parallel.
