DSP_A and DSP_B are not interchangeable. The timing used by the codec in DSP mode is consistent with DSP_A. This is verified with an EG25-G modem connected to AIF2, as well as by comparing with the BSP driver.
This can only break things for existing systems using stable, if they haven't noticed a problem with DSP B they'll certainly notice failing to set up the DAI at all without it.
Are you suggesting that I drop this patch entirely, or only that I remove the CC to stable (and/or Fixes: tag)? Is this something that can't be removed once it's there, or is the concern about making user-visible changes on stable?
Remove the stable tag, if someone is relying on the DSP B support in stable this will break it.
