If the codec is not the clock master, the MCLK needs to be
synchronous to both I2S_SCL ans I2S_LRCLK. We do not have that
on Haikou, causing distorted audio.

Before:

 Running audioloopback.py script on Ringneck, 1kHz
 output sine wave is not stable and shows distortion.

After:

 10h stress tests audioloopback.py failed only one time.
 That is 0.00014% failure rate.

What is TSD? Why it is in the subject prefix?

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.

Best regards,
