We'd expect you to have tested it. You can drop this tag.

However, it would indeed be nice to have someone with an A10 testing
it. Chen-Yu?

This is not the branch you should be basing your patch on. This is an
ASoC patch, base it on the ASoC tree.

You have a bunch of checkpatch errors and warnings, make sure you fix
them.

You're doing several things in this patch:
- Reworking things to be able to have different widgets and routes
between the compatibles
- Add new controls.

Please make two separate patches.

And this belongs in a separate patch too.

Why is this moved?

I guess a single codec is enough :)
