Hi Vladimir,

A pity. I would have liked to have you in the room. Let's see if we can
get enough input from you via mail here.

We have only 45 minutes, this will not allow to review specific
implementations. I want to give an overview of existing implementations
with pros/cons...

... and I'd appreciate support here from you, like your summary of the
back then discussion (from where I can dive deeper if needed).

Also, with Luca's new series we discussed some scenarios which can
happen WRT to I2C address conflicts. Maybe you could comment on them,
too? As I read the old thread, you have a hardcoded aliases using
"ti,i2c-bridge-maps". This means you can't have own DTSI files for e.g.
add-on modules, do I get this correctly?
