Power Management on Zephyr
summary
Adds residency-based power policy and TI power manager integration to support CC1352R1 on Zephyr, mapping idle/standby/shutdown to Zephyr states and using TI APIs to gate domains and peripherals. Uses EnergyTrace measurements with 1 MΩ range and 256 ksps, reporting ~0.85–1 µA in standby and ~3 mA active. Implements device PM callbacks, GPIO wake, and a Python energy-pi script that flashes binaries and plots CSV output; shutdown current is below the trace floor so a multimeter verifies it.
