From fee04adc751747a476ce832be26a488df01f852e Mon Sep 17 00:00:00 2001 From: Pau Espin Pedrol Date: Wed, 17 Jun 2020 17:23:57 +0200 Subject: Introduce bts_shutdown FSM Using an FSM here will allow for more complex ordered shutdown procedures, like power ramp down, waiting for TRX deact asyncrhonously, etc. Current commit leaves everything in place already prepared to implement ramp down, which will be implemented in next commit in the series.
