Where did you find the TWL3025 datasheet?  Wading through 52rd.com, or
is there some other source I'm unaware of?

Hmm, interesting.

What OsmocomBB-supported phones use TWL3014?

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?
