+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!
