Thank you for your patch. There is something to discuss/improve.

Your patch is corrupted because you modified it after creating it. It
won't apply correctly and won't work. The bot's response with error is
about this.

Except broken patch, here are some more comments:

Subject: drop driver. Bindings are about hardware, not drivers.

It's not a DAI?

Drop the header, you do not use it.

also drop label (max98363).
