My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

If the block is called 'AFE PCM controller', then perhaps use some of 
that for the name instead of just 'audio'.

What does that file contain?

No need to provide generic descriptions of common properties, so the 
reference can just be dropped.

Don't need quotes.

What value disables/enables?

items:
  enum: [ ??? ]

OK. Is "mediatek,mt8188-afe" better for you?

"../reserved-memory/reserved-memory" contains the detail of reserved-
memory, and it's replaced by reserved-memory.yaml now.
I will remove the item in V2, because it's still not supported in the
current code base.
Next time I will remove the description, when I add common properties.

Did you mean I should delete this line, and only leave description

Max channel number is 16, so the value could be 0~15 in the array.
For example, when 0 and 2 are configured, the input channel 0 and
channel 2 won't be put in data on memory.

I will add enum: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
here.
