Notes from OsmocomBB tinkerer steve-m, relayed to me (Mother Mychaela) through
Vadim, indicate that:

* Calypso TSP signals going to Rita xcvr are wired per canon: TSPEN2 for strobe,
  TSPACT0 for reset.

* TSP controls to the PA are also TI-canonical: TSPACT9 for enable, TSPACT3 for
  band select.

* The two antenna switch controls (Tx low band, Tx high band) exactly match TI
  Leonardo, specifically the cheapened 2-band version of that canonical
  platform: TSPACT1 is Tx high band switch, TSPACT2 is Tx low band switch, both
  inverted per canon.

But here is the part that deviates from canon: Iota TEN is apparently wired to
Calypso TSPEN1 instead of canonical TSPEN0!
