I just noticed that you seem to have dropped the nn_core_count property
from this HWDB entry when reworking the series according to my
feedback. I assume that you are fine with me fixing this up in the
etnaviv tree by using the hunk from your previous patch "[PATCH v4 6/7]
drm/etnaviv: Add nn_core_count to chip feature struct".

If you see any issue with that, please let me know.

Regards,
Lucas
