I agree.

IMO, it makes no sense to keep merging anything on Hantro G2 HEVC
support, until the BLK-CTRL part is ready [1]. Without that, we can't
test anything
so we may introduce regressions without knowing.

Also, I think it's time to start discussing the HEVC uAPI as a whole,
with the goal is having a stable interface that can be used by userspace
frameworks (GStreamer).
