I'm not sure there's support for adding kcontrols to BE link widgets in alsa topology atm. You might want to check that.
I think the intention here is to add an associated kcontrol (not in any audio path/graph) for each SSP. The DAI FW driver will need to register a cmd() callback to support this and maybe a bespoke topology tuple will need to be used to bind the kcontrol to the SSP port.
yep, that is what we did for 0.9.5.
