I think TI consistently writes it "FPD-Link III". If you rename it,
please do so through the whole series.
Indeed, good point.

Is the -q1 suffix needed, are there other variants ?
I'm not sure, but I couldn't see at a quick glance. I don't know what
the -q1 means. Even if many of the FPD-Link devices have -q1, there are
models without -q1, like DS90CF366. Oh, all those non-q1s seem to be
from Catalog, and -q1 versions from Automotive. But the -q1 seems to be
part of the model name, so... Maybe it's better to keep it.

I'd add

Ok.
