We're checking topology feature requests for platforms later than 
Skylake. We expect to finish the feature collection this or next week. 
Then we can give a more accurate schedule.

Now the unstable ABI is mainly for ASoC DAI and DAI links. Platforms 
later than Skylake need them. We're checking the gap between existing 
ABI and new requests.
