What errors are those? Nothing you've posted so far looks like an error to

That's from not having a devnode for "amp-mute", "headphone-mute" or
"headphone-detect". I don't think that's a problem.

That's just because the tas3001 driver code (the mixer for the
Tumbler/Texas) is searching all available I2C buses, and the first one
doesn't have what it's looking for.
