commit 879a19e153a1143e5acebd85c241adb3ddc8aa46 Author: Marco Casaroli <[email protected]> AuthorDate: Wed Oct 7 18:06:43 2026 +0200 boards/rp23xx: Add pm configurations for the Pico 2 and Pico Plus 2. raspberrypi-pico-2:pm and pimoroni-pico-2-plus:pm enable the PM standby and dormant states with the greedy governor, suspend to RAM with the BOARDIOC_RP23XX_SUSPEND boardctl() command, and the RTC alarm. The console receive pin (GPIO 1) wakes the chip, and the dormant state is refused for 30 s after boot so that a debugger can attach. The Pico Plus 2 configuration also adds its PSRAM to the heap.
