What makes you say that the symmetric_rates flag can't be used to cover this case? What you describe above is hte normal reason for needing to enforce symmetric_rates. The driver should be able to check if the flag has been set just as well as the core is.
Got it, How about the following modify?
if (dai->symmetric_rates) regmap_update_bits(i2s->regmap, I2S_CKR, I2S_CKR_TRCM_MASK, I2S_CKR_TRCM(val));
Yes, something like that. You'll need to check both links in the DAI and the DAI link itself rather than just your own DAI but we should have a helper function for that - I'll add one, look out for a patch shortly.
