Why is this declared as a single element array? It just makes all the usages look odd for no obvious gain.

This should be dev_dbg() at most, _info() will be too noisy in the logs. Same for a lot of functions, including the stream callbacks.

This should just be removed entirely, there's trace in the core if you need logging in production systems - the tracepoints in particular are good for just leaving on all the time without adding overhead.

Please write normal conditional statements to improve legiblity.
- if (rate == 44100)
regmap_write(afe->regmap, AFE_ASRC_2CH_CON3, 0x001B9000);
- else if (rate == 32000)
regmap_write(afe->regmap, AFE_ASRC_2CH_CON3, 0x140000);
- else
regmap_write(afe->regmap, AFE_ASRC_2CH_CON3, 0x001E0000);
This would be better written as a switch statement.

Are you sure this isn't system dependant?
Hi Mark, Yes, this is a system independent setting. And I fixed other comments you pointed out then send "PATCH v4".
