ipc_dai_config is a shared structure from host to DSP, it should not be used to save some SSP only stauts and it may also not be generic. This change is made for this reason as your last two comments about adding flag in
struct sof_ipc_dai_config and struct dai with this SSP only status.
but loopback is not just for SSP, other non Intel DAIs also support it.
Humm, not sure I agree here with the logic.
Some non-Intel DAIs support LBM. One Intel DAI out of 4 - the SSP - supports LBM
-> so what is the reason for making this field generic? It creates a case where LBM would be configurable for Intel DAIs who don't support it...
