Could you please be more specific at your test cases?

Which board? Whose is the DAI master? Which sample rate?

There are quite a few clean-up patches of SSI driver being merged.
Would you please try to revert/bisect the changes of fsl_ssi driver

If there is a regression because of one of the changes, I will need
to fix it.
