Unfortunately, I can't accept this patch.
It will be strange sound if you change clk master to SSI (*1).
Additionally, it needs audio_clk settings for SSI master,
but, it needs special limitation (*1).
(*1 HW connection reason)
And format change left_j -> i2s is no meaning on Lager board case

Best regards

Thanks for your analysis.
I am marking this patch as "rejected".
