I believe that the codenames refer to specific generations for each
function, rather than to functions like DBB/ABB/RF. For example, it
seems that Calypso succeeded Hercules in the DBB role, and Rita
succeeded Clara in the RF role.
I remember seeing somewhere that Iota's successor was/is Syren,
whereas its predecessor in the ABB role was Nausica. But if TWL3016
and TWL3025 are both Iotas, which chip is then Syren? Does anyone
know?

Well, some time ago I diffed the TWL3014 and TWL3025
datasheets,
Where did you find the TWL3025 datasheet? Wading through 52rd.com, or
is there some other source I'm unaware of?
there is no technical difference at all (only 3014
replaced with 3025,
and some minor formatting changes).

I suspect that TI renamed
the chip because of some changes in the manufacturing process.
Hmm, interesting.
Given that both chips work fine with osmocom (with the
same revision of
DSP rom code on the Calypso side of things),
What OsmocomBB-supported phones use TWL3014?

No it doesn't.

Is it a Iota variant or a Syren variant?
I
think they're all called "Iota" that's a generic designation for the
ABB.

I always tought that Iota was a generic designation for then ABB in
the TI leonardo platform.
And then you also had specific codenames for the individual chips:
Syren is the TWL3016.
Triton is TWL3029.
But from re-reading various docs, it indeed might be a wrong
impression and Iota designation seems specific to TWL3014.
But seriously ... who cares ... If you need to refer to a specific
chip model, use the part number and not some obscure name.
Cheers,

Search Google for "TWL3025 SWRS021", last hit.

Motorola C155, V171, Pirelli DP-L10.

Both TWL3014 and TWL3025 are Iota, TWL3016 is Syren.
