Yes, but I will remove the ldc files from FW and move to topology repo.
Jaroslav, is I'm assuming it's OK to move the ldc files into the same
repos as topology ?

I'm assuming alsa-topology may follow alsa versioning ? But maybe best

Linux FW repo just has some tags for dates, but seems to be a monthly
tag.
