Looks like I`ve failed to double-check the datasheet here, sorry for that,
I`ll try to remember that in future occasions.

Agree, actually, I was wondering here if the lidar-lite-v2 ref that I`ve found
when adding the grmn,lidar-lite-v3 is actually a trivial. 
It was originally added as trivial over txt file at [1] and then converted to yaml but
it looks like it is also not a trivial considering some refs at [2] and [3] (not official docs).
At those refs, I can see the same enable/mode pins.

Should we also move that out of trivial in a dedicated binding or should we keep as is
considering those docs are not official/device is very old?
Tks and regards!
