I'd rather drop 346 because there is no compatible for that one anywhere.
No need to resend, I can fix it here...

If you drop adi,adxl346, checkpatch will start complaining if it encounters
it in a .dts.

Boah, this is annoying. That means we need an 346 entry even if it is
not different from 345 (which is fine by me).

If checkpatch does it this way, that means the rule of thumb is to
*always* have a dedicated compatible entry? Can someone confirm this?

Why did we discuss then? Now, I am confused as well...
