A single compatible for 3 devices is highly suspect. What is
different between these devices?
The maximum supported current is different.
-2: 135A
-1A: 150A
-4A: 200A
Programming is exactly the same, which is why I had asked the submitter to use
a single compatible property. Sorry for that if it is inappropriate.
Is there some guidance explaining when to use a single vs. multiple compatible
properties for different chip variants ?
Note that there are also LTP8803-1A which supports 160A, and LTP8802A-1B
which supports 140A. Maybe there are more, but those are the ones I can find in
public. I don't know if there is a difference from programming perspective compared
to the LTP8800 chip variants; the datasheets are too vague to be sure. It would be
useful to know if those chips should get separate compatible entries if programming
is the same.
Thanks,
