What is milli unit? Isn't gain in dB, so maybe you want mB? Quite
unpopular to see mB, but we cannot use 1/100 of dB, so I could
understand it.
 

Actually, the gain is expressed in V/V, not in dB. I may have phrased it poorly, but since
there are fractional values like 0.364 and 0.143, I chose to represent it
in milli-units.  

Why your reply to is corrupted:

What sort of unit is milli-unit? Isn't this 1/1000 of some BASE unit,
but you do not have here a base?

I think you want just basis point if this is V/V (already in common
property suffixes)

Nice. I didn't know about -bp.   That does sound like a good choice for ratio
stuff and here would be 100x larger actual values which is fine.

Yes, it would be, but the here it is 1000x larger than the
actual value (1/1000 V/V). I don't see another unit in
property-units.yaml for this specifc case. Maybe using -milli suffix
like in 'adi,ad4000.yaml' and 'adi,ad7380.yaml'?
