You treat my feedback selectively... some things improved, but not
everything. I am literally repeating the same and expect different
results from you... isn't that the definition of insanity?

Let me paste ignored parts:

1. Your patches are still not correctly threaded. There is no threading
at all.

I said it multiple times. What else should I say here?

2. Subject: ASoC: dt-bindings: Add tas2781 amplifier
(drop the full stop - why did you add it there?)

3. Missing changelog under ---.
I mentioned it already few times, didn't I?

Drop the reference to gpio.txt.

I give up. I spent too much time on it while being also ignored a bit
too much.

You got four times my comment that your threading is wrong. You never
replied to that comment that something is not clear. Threading is still
wrong - there is no user of this binding here.

Don't need '|' unless you need line endings preserved. Wrap lines at 80

Express as constraints instead:

items:
  minimum: 0x38
  maximum: 0x40

Or was this the range of the slot addresses?

The description doesn't add anything. Drop.

I2C

Be consistent.

Do these vary? Or the slot addresses are fixed and which slots are used 
varies?

I tend to think the I2C addresses should all be in 'reg'.
