Hi Peter!

Your plan is fine so far.

We might add some more comments to group devices obviously together,
since those looking first time at it are a bit lost.

For such i2c IR limits, we have your and Eddi's comments.

Since we can't help it easily, Peter D. should suggest the older version
of the MSI A/D for auto detection. It won't make anything more worse on
that not fully clear Vivanco stuff, except Hartmut might have ideas.

Cheers,
Hermann
