OK, so the story here is during the first submissions, I had something
similar (i2c-hid or so). I was then told that it was not necessary to
use "i2c" in the name given that it was an I2C driver already. But it
looks like when I created the device tree binding, I forgot about it and
messed around a little bit, again.

My apologies, and:

Would it make sense to remove the other name ("hid") which should have
less compatibility issues (all the users *should* be in the kernel
tree).

Cheers,
Benjamin
