An ATR is a device that looks similar to an i2c-mux: it has an I2C
slave "upstream" port and N master "downstream" ports, and forwards
transactions from upstream to the appropriate downstream port. But is
is different in that the forwarded transaction has a different slave
address. The address used on the upstream bus is called the "alias"
and is (potentially) different from the physical slave address of the
downstream chip.
Add a helper file (just like i2c-mux.c for a mux or switch) to allow
implementing ATR features in a device driver. The helper takes care or
adapter creation/destruction and translates addresses at each transaction.
First of all, thank you for bringing this work on!

Hmm... Are you going to maintain this? Or Review? Why not?
We haven't discussed with Luca if he wants to maintain this (this is
mostly his code). But, indeed, I should add my name there.
I think at this point you are probably in a better position to be the
maintainer, but I'm OK with being listed here as reviewer (R:).
Ah, would you please use my bootlin dot com address here?
Ok, I've added your bootlin address as R:
Tomi
